Reservation Deadlines and Early‑Bird Discounts for 2026 Tours

The 2026 schedule for exclusive cenote night‑swim tours departing from Mérida follows a tiered reservation calendar that aligns with the region’s peak tourist periods and the seasonal availability of each cenote. All tours are limited to a maximum of 12 participants per night to preserve the intimate atmosphere and protect the natural environment. Reservations must be secured within the specified windows to guarantee a spot and to qualify for the applicable early‑bird discount.

Key Reservation Milestones

1. Initial Release (12‑Month Window) – The first batch of high‑season dates becomes available in January 2026. The release follows a “first‑come, first‑served” allocation; once the 12‑person limit is reached for a given night, the date is closed to further bookings. Early‑bird pricing of 15 % applies automatically at checkout for all reservations completed before the 30‑day cut‑off.

2. Mid‑Year Release (9‑Month Window) – Shoulder‑season dates open in June 2026. The same allocation rules apply, with a reduced discount of 10 % for reservations confirmed before the 21‑day cut‑off. This window also introduces a “flex‑date” option, allowing guests to shift their night‑swim within the same month without penalty, provided the new date remains available.

3. Final Release (6‑Month Window) – Low‑season dates appear in January 2026. The 5 % discount is automatically applied to bookings finalized before the 14‑day cut‑off. Because low‑season demand is lower, a limited “last‑minute” release may occur 48 hours before departure, offering no discount but guaranteeing a spot for any remaining capacity.

Group and Repeat‑Visitor Incentives

• Group Discount – Parties of six or more participants receive an additional 5 % off the already discounted rate, provided the group books together in a single transaction before the respective cut‑off date.
• Loyalty Credit – Guests who have completed a cenote night‑swim tour in 2026 are credited with a 3 % discount on any 2026 reservation, stackable with the early‑bird and group discounts, but capped at a total discount of 20 % per booking.

Cancellation and Modification Policy

• Free Cancellation – Cancellations made more than 30 days before the scheduled night incur no fee and automatically release the spot back to the reservation pool.
• Partial Refund – Cancellations between 30 and 14 days before departure receive a 50 % refund of the prepaid amount; the remaining balance is retained as a re‑booking credit valid for any 2026 tour.
• No Refund – Cancellations within 14 days of the tour date are non‑refundable, though the prepaid amount may be transferred to a future date within the same season, subject to availability.

Reservation Process Overview

All bookings are processed through the centralized online reservation platform. The platform displays real‑time availability, automatically applies the relevant early‑bird discount, and calculates any additional group or loyalty reductions. Payment must be completed in full at the time of reservation to secure the discount. Upon successful payment, a confirmation code is generated; this code serves as the only reference required for check‑in at the designated meeting point in Mérida.

Adhering to the outlined deadlines ensures eligibility for the maximum discount tier and secures placement on the preferred night‑swim date. Travelers planning multiple tours across different seasons should coordinate bookings early to take advantage of overlapping discount windows and group‑rate opportunities.

Available Tour Packages: Standard, Premium, and Private Night Swims

Standard Night Swim – This entry‑level offering is designed for solo travelers and small groups seeking a guided plunge into a single cenote after dark. The itinerary includes a 45‑minute pre‑departure briefing on safety, local legends, and nocturnal wildlife, followed by a 60‑minute swim under LED‑lit floating lanterns. Guests receive a complimentary biodegradable glow‑in‑the‑dark wristband, a light snack of fresh fruit, and a reusable water bottle. The 2026 price is US $85 per person, with a minimum of two participants per tour. Children ages 6‑12 qualify for a 20 % discount; children under six are not permitted for safety reasons.

Premium Night Swim – The premium tier expands the experience to two cenotes, incorporates a cultural immersion segment, and adds upscale amenities. After the same safety briefing, the group explores the first cenote for 45 minutes, then transfers by climate‑controlled van to a second, larger cenote renowned for its crystal‑clear waters and natural acoustic chamber. A professional photographer captures underwater images, and guests receive a digital gallery link within 48 hours. The package includes a gourmet hors d’oeuvre platter, locally sourced mezcal tasting, and a souvenir eco‑friendly lantern. Pricing for 2026 is US $145 per adult, with a minimum party size of four. A senior discount of 15 % applies to travelers 65 years and older; group rates of 8 + participants reduce the per‑person cost to US $130.

Private Night Swim – Tailored for couples, families, or corporate groups desiring exclusivity, the private tour grants full control over schedule, cenote selection, and optional add‑ons. A dedicated guide curates a personalized itinerary that may include up to three cenotes, a private underwater sound system, and a custom menu prepared by a local chef. Luxury amenities such as heated blankets, aromatherapy diffusers, and a post‑swim spa massage are available on request. The base rate for 2026 is US $295 per night for up to six guests; each additional guest incurs a US $35 surcharge. A refundable security deposit of US $100 per booking is required.

Reservation Process & Payment Details – All tours are booked through the official online portal, which accepts major credit cards and secure digital wallets. Reservations must be made at least 48 hours in advance for Standard and Premium tours; Private Night Swims require a 7‑day lead time to accommodate custom logistics. Upon booking, a 30 % deposit secures the slot; the balance is due 24 hours before departure. Cancellations up to 48 hours prior receive a full refund of the deposit; later cancellations forfeit the deposit. Prices are listed in U.S. dollars and include all taxes, guide fees, and environmentally responsible waste disposal.

The Premium Night Swim consistently yields the highest satisfaction scores because it balances adventure with cultural depth while keeping group sizes manageable. Travelers who prioritize photography should request the professional photographer add‑on at booking, as spots fill quickly during peak season (December–April). For families, the Private Night Swim’s flexible itinerary justifies the premium cost, especially when combined with the optional spa massage, which adds a wellness dimension rarely found in cenote tours. Booking early and confirming any dietary restrictions ensures a seamless, unforgettable nocturnal dip.

Age and Physical Requirements for Nighttime Cenote Swimming

Nighttime cenote tours in the Mérida region combine the allure of natural subterranean pools with the mystery of darkness, creating a unique adventure that demands specific age and physical criteria to ensure participant safety and enjoyment. Operators base their requirements on the characteristics of each cenote, the logistical challenges of low‑light navigation, and the need to respond quickly to emergencies.

Minimum Age

Most tour providers set a firm minimum age of 12 years for solo participants. Children younger than 12 may join only when accompanied by a parent or legal guardian who is an active participant in the swim. The age threshold reflects the cognitive maturity needed to understand safety briefings, follow underwater signals, and react appropriately to sudden changes in water conditions. For cenotes with steep vertical drops or narrow passages, the minimum age may rise to 14 years, and operators will clearly state this in the reservation details.

Maximum Age

There is no upper age limit, but individuals over 70 years are advised to consult a physician before booking. Age‑related concerns typically involve cardiovascular health, joint flexibility, and the ability to handle prolonged exposure to cool, humid environments. Operators may request a medical clearance form for guests who disclose chronic conditions such as hypertension, heart disease, or severe arthritis.

Swimming Proficiency

A competent, non‑panic swimming ability is mandatory. Guests must be comfortable in deep water, capable of treading water for at least three minutes, and able to perform basic underwater navigation. Certification in basic lifesaving or a recognized swimming level (e.g., Red Cross Level 2 or equivalent) is often required for participants under 18 years. For adults, a brief in‑water assessment is conducted prior to entry; failure to demonstrate adequate skill results in a mandatory switch to a guided float‑assist option, which may incur an additional fee.

Physical Fitness

Cenote night swims involve climbing modestly steep limestone steps, wading through shallow sections, and occasionally crawling through tight chambers. A baseline level of cardiovascular fitness—equivalent to being able to walk briskly for 15 minutes without undue fatigue—is expected. Guests with recent surgeries, severe respiratory conditions (e.g., uncontrolled asthma), or musculoskeletal injuries should refrain from participation. Operators typically request a short health questionnaire at the time of reservation to screen for such issues.

Weight and Size Considerations

While there is no strict weight limit, extremely high body mass can affect buoyancy and maneuverability in confined spaces. Tour guides assess each group’s composition and may advise alternative arrangements for guests whose size could impede safe movement through narrow passages.

Accessibility

Only a minority of cenotes are fully wheelchair‑accessible; most night‑time sites feature uneven terrain and low ceilings. Guests requiring mobility assistance should select tours explicitly labeled as “accessible” and confirm the presence of handrails, ramps, and wider entry points during the reservation process. Even in accessible cenotes, a minimum swimming ability remains essential because participants must still navigate water sections.

Health Precautions

Cold‑water immersion can trigger hypothermia in susceptible individuals. Cenote water temperatures at night typically range from 22 °C to 26 °C. Guests are advised to wear a thermal neoprene wetsuit (minimum 3 mm thickness) and a life‑vest equipped with a reflective strip for visibility. Those with known allergies to limestone dust or who are prone to ear infections should bring earplugs and consider prophylactic measures.

Safety Gear and Briefings

All participants receive a pre‑dive safety briefing covering hand signals, emergency exit routes, and the use of headlamps. Mandatory gear includes a certified dive mask, snorkel, non‑slip water shoes, and a personal flotation device. For guests who do not meet the swimming proficiency criteria, a guided float‑assist system—featuring a tethered buoyancy aid and a dedicated guide—ensures safe participation.

By adhering to these age and physical requirements, travelers can fully appreciate the ethereal beauty of Mérida’s nocturnal cenotes while minimizing risk. Reservations that align with the outlined criteria help operators maintain high safety standards and deliver a memorable, immersive experience for all guests.

Included Amenities: Guided Lighting, Safety Gear, and Refreshments

All Merida exclusive cenote night‑swim tours incorporate a core set of amenities designed to maximize visibility, ensure participant safety, and provide light sustenance during the underwater experience. These components are factored into the base price quoted for each tour and are standard across the three primary night‑swim packages (Standard, Deluxe, and Premium). The following outlines the specific elements that guests can expect, as well as the variations that differentiate each package.

Guided Lighting

*Underwater LED Pathway* – A low‑profile, waterproof LED strip is installed along the main swim route in each cenote. The strip emits a soft, blue‑white glow that delineates the swimming corridor without disrupting the natural darkness of the cavern. The pathway is powered by rechargeable battery packs that provide up to four hours of continuous illumination, sufficient for the longest scheduled swims (approximately 2.5 hours).

*Hand‑Held Submersible Torches* – Every participant receives a personal, waterproof LED torch with an adjustable beam (wide for ambient viewing, narrow for focused inspection of geological formations). The torches operate on sealed lithium‑ion cells, offering a minimum of 90 minutes of runtime at maximum brightness. For the Deluxe and Premium packages, the torches are equipped with a red‑light mode to preserve night‑vision adaptation during extended underwater observation.

*Surface Spotlights* – On the cenote’s surface, high‑intensity, dimmable spotlights are positioned to illuminate entry and exit points, as well as the surrounding limestone walls. The spotlights are synchronized with the underwater pathway to create a seamless transition between surface and sub‑surface lighting. Premium‑package guests receive an additional portable spotlight that can be directed toward specific formations upon request.

Safety Gear

*Life Vests* – All guests are fitted with a CE‑certified, buoyancy‑controlled life vest sized to individual body measurements. The vests are made of quick‑dry neoprene and feature reflective trim for visibility in low‑light conditions. The Standard package includes a single‑size vest for each participant; Deluxe and Premium packages provide a choice of three sizes (S, M, L) to ensure optimal fit.

*Protective Headgear* – Soft‑shell, water‑resistant helmets are supplied to protect against low‑lying stalactites and accidental impacts with the cenote ceiling. The helmets include an integrated headlamp (used only for emergency egress) and a detachable chin strap for secure placement.

*First‑Aid and Rescue Equipment* – Each tour boat carries a compact first‑aid kit stocked with antiseptic wipes, bandages, and waterproof splints. A certified rescue diver equipped with a surface‑supplied air line and a portable defibrillator is on standby for the entire duration of the swim. The Deluxe and Premium packages add a secondary rescue diver and a portable oxygen cylinder for enhanced emergency response capability.

*Briefing Materials* – Prior to entry, guests receive a printed safety briefing that outlines hand signals, emergency procedures, and environmental guidelines. The briefing is reinforced by a short video presentation displayed on a waterproof tablet mounted on the boat’s deck.

Refreshments

*Hydration* – Two 500 ml bottles of filtered, chilled mineral water are provided per participant. The water is stored in insulated containers to maintain a cool temperature throughout the night swim.

*Fruit and Light Snacks* – A selection of locally sourced fruit (pineapple, mango, and watermelon) is sliced and served in individual, biodegradable containers. In addition, a small portion of salted tortilla chips accompanied by a mild lime‑chili dip is offered as a light snack. The Deluxe package upgrades the fruit selection to include papaya and guava, while the Premium package adds a small serving of traditional Yucatán tamales.

*Optional Evening Beverage* – Guests may request a complimentary glass of fresh coconut water or a non‑alcoholic hibiscus refresher. For Deluxe and Premium guests, a single‑serve artisanal craft soda (e.g., tamarind or guava) is included at no additional charge.

All amenities are replenished after each tour to maintain hygiene standards. Reservations must indicate any dietary restrictions or special lighting preferences at least 48 hours in advance to allow the operator to accommodate individual needs. The inclusive nature of guided lighting, comprehensive safety gear, and thoughtfully curated refreshments ensures that the night‑swim experience remains both charming and secure for all participants.

5. Rescheduling Options

• Guests may reschedule to another available night‑swim date within the 2026 season without penalty, provided the request is made at least 7 days before the original tour date. The original payment is transferred to the new reservation.
• Rescheduling requests made between 48 hours and 7 days before the tour are subject to a 15 % administrative fee, deducted from the original payment before applying the balance to the new date.
• Requests made less than 48 hours before the tour are treated as cancellations under the applicable window and are subject to the corresponding refund or credit terms.

6. Processing Time and Method

All refunds are processed to the original credit or debit card used for booking. Refunds are initiated within 48 hours of the cancellation confirmation and typically appear on the cardholder’s statement within 7–10 business days, depending on the issuing bank. Credits are issued as a unique voucher code, valid for any cenote night‑swim tour in 2026 and redeemable online or at the ticket office.

7. Travel Insurance Recommendation

Given the tiered refund structure, travelers are strongly encouraged to secure travel insurance that covers trip cancellation for medical or personal emergencies. Insurance payouts are independent of the operator’s refund schedule and may provide additional reimbursement beyond the percentages outlined above.

8. Documentation Required for Refunds

• Cancellation confirmation email (automatically generated).
• For force‑majeure personal emergencies, a copy of relevant documentation (e.g., medical certificate, death certificate).
• For credit issuance, the voucher code will be sent via the email address provided at booking.

9. Special Promotions and Discounted Rates

Bookings made using promotional codes or early‑bird discounts are subject to the same cancellation windows, but the refund percentage is calculated on the discounted total price. No additional refunds are provided for the value of the discount itself.

By adhering to these guidelines, guests can plan their cenote night‑swim experience with clarity on financial obligations and the flexibility available for unforeseen changes.

Payment Methods Accepted and Installment Options for Large Groups

For the 2026 season, operators of exclusive cenote night‑swim tours in the Mérida region accept a standardized set of payment instruments designed to accommodate both individual travelers and organized parties of ten or more participants. All transactions are processed in Mexican pesos (MXN); a real‑time conversion rate is applied when the reservation is entered in U.S. dollars (USD) or euros (EUR).

Core Payment Instruments

1. Major Credit Cards – Visa, MasterCard, American Express, and Discover are processed through PCI‑compliant gateways. Cardholders benefit from automatic currency conversion and the option to select a three‑ or six‑month installment plan directly at checkout, subject to the issuing bank’s terms.

2. Debit Cards – Visa Debit and Maestro are accepted for full‑amount payment. No installment functionality is available for debit transactions.

3. Cash (MXN) – On‑site cash payment is permitted for walk‑in bookings made less than 48 hours before the scheduled departure. Cash is not accepted for advance online reservations.

4. Digital Wallets – Apple Pay, Google Pay, and Samsung Pay are linked to the underlying credit or debit card and follow the same installment rules as the associated card.

5. Bank Transfers – For large groups, a direct bank transfer to the operator’s corporate account is common. Transfer details are provided after the reservation is confirmed. A 2 % surcharge compensates for processing fees.

6. Travel Vouchers and Tour‑Operator Credits – Accredited travel agencies can apply prepaid vouchers or credit balances toward the total cost. Voucher redemption follows the same schedule as cash payments; installment plans are not offered on voucher portions.

Installment Structures for Groups of Ten or More

Large parties benefit from tiered payment schedules that reduce upfront cash flow pressure while guaranteeing reservation security. The following structures are standard across the majority of licensed tour providers in the Yucatán Peninsula for the 2026 calendar year.

All installment payments may be made via the accepted credit‑card or bank‑transfer methods. When a credit‑card installment plan is selected, the issuing bank divides the amount into equal monthly charges; the operator records the full price at reservation and the card network handles the disbursement schedule.

Financing Partnerships

Several operators have partnered with regional fintech firms to offer zero‑interest, 12‑month financing for groups exceeding 30 participants. Eligibility requires a corporate tax identification number (RFC) and proof of a minimum annual turnover of MXN 2 million. Approved groups receive a single invoice reflecting the total cost; the fintech provider collects monthly payments directly from the corporate account.

Refund and Cancellation Policy Linked to Payment Type

• Credit‑Card Payments – Full refund for cancellations made more than 14 days before the tour; 50 % refund for cancellations between 14 and 3 days; no refund for cancellations within 72 hours. Refunds are processed to the original card within 7‑10 business days.
• Bank Transfers and Cash Deposits – Refunds are issued via the same method (bank transfer or cash) following the same time‑frame schedule.
• Voucher Portions – Non‑refundable; any unused voucher value may be re‑applied to a future booking within the same calendar year.

Currency and Exchange Considerations

When reservations are entered in USD or EUR, the exchange rate applied is the official Banco de México rate at the moment of booking confirmation. A 1.5 % conversion margin is added to cover administrative costs. Travelers using credit cards that perform automatic foreign‑exchange conversion will see the final charge in their home currency, inclusive of the operator’s margin.

Documentation Required for Group Payments

• Signed group agreement outlining the payment schedule.
• List of participants with full names as they appear on government IDs.
• For bank‑transfer or fintech financing, a copy of the corporate RFC and a recent financial statement.

These payment and installment frameworks ensure that large groups can secure exclusive cenote night‑swim experiences while maintaining financial flexibility throughout the 2026 booking cycle.

Seasonal Availability: Peak vs. Off‑Peak Night Swim Dates

Seasonal Availability: Peak vs. Off‑Peak Night Swim Dates

Climate Influence on Night‑Swim Scheduling

The Yucatán Peninsula’s climate dictates the most reliable night‑swim windows. The dry season (November – April) offers clear skies and lower humidity, creating optimal visibility for underwater illumination and a comfortable ambient temperature for guests. During the rainy season (May – October), afternoon thunderstorms are common; tours are therefore scheduled for later evenings (10:30 pm – 12:30 am) when the probability of precipitation diminishes. Operators reserve additional buffer days in the rainy months to accommodate weather‑related cancellations without penalizing guests.

Lunar Cycle Considerations

Cenote night swims are most popular during a waning or new moon, when minimal moonlight enhances artificial lighting effects and reduces surface glare. Peak‑season operators block out dates that coincide with a full moon (approximately every 29.5 days) and offer limited “Full‑Moon Experience” slots at a premium surcharge (+10 %). Off‑peak periods retain the standard lunar‑adjusted schedule, allowing guests to select any available night regardless of moon phase, though lower demand typically results in reduced pricing.

Holiday and Event Impacts

National holidays—Semana Santa (April), Día de los Muertos (November 1‑2), and the December holiday stretch—trigger spikes in international arrivals. Operators raise capacity limits to 10‑12 guests per cenote and apply the Late‑Peak pricing tier. Conversely, the week following New Year’s Day (January 2‑8) experiences a dip in bookings; operators often release additional off‑peak slots and may bundle night‑swim experiences with daytime cenote tours at a combined discount (‑20 % of the summed individual rates).

Reservation Mechanics

All 2026 night‑swim tours require a non‑refundable deposit of 30 % at the time of booking, with the balance due 30 days before the scheduled night. Reservations are confirmed on a first‑come, first‑served basis within the designated window. For peak‑season dates (June – August, major holidays), the reservation window shortens to 60 days, and a 48‑hour cancellation policy applies; cancellations made earlier than 48 hours receive a 50 % refund of the deposit, while later cancellations forfeit the deposit entirely. Off‑peak dates retain a more flexible 72‑hour cancellation window with a 25 % deposit refund.

Capacity Management and Safety Protocols

During peak months, operators enforce stricter capacity caps (8‑10 guests) to comply with local safety regulations concerning night‑time water activities and to ensure adequate guide‑to‑guest ratios (1:2). Off‑peak periods allow larger groups (up to 15 guests) because lower ambient temperatures reduce the risk of hypothermia and the reduced tourist density eases logistical constraints such as transportation to remote cenotes.

Summary of Seasonal Availability

• Peak Night Swims (June‑August, major holidays): Higher demand, reduced group size, premium pricing, shorter reservation lead time, stricter cancellation terms.
• Off‑Peak Night Swims (January‑March, September‑October): Lower demand, larger groups permitted, discounted rates, longer reservation lead time, more lenient cancellation policy.
• Early‑Peak (April‑May) and Late‑Peak (November‑December): Moderate demand, intermediate pricing, balanced group sizes, reservation windows adjusted to reflect seasonal travel patterns.

Understanding these seasonal dynamics enables travelers to align their cenote night‑swim aspirations with optimal pricing, availability, and safety conditions for the 2026 travel year.

Transportation Details: Pick‑up Locations and Travel Times from Mérida

All exclusive cenote night‑swim tours depart from designated pick‑up points within the Mérida metropolitan area. Operators coordinate a single departure window for each tour, typically between 20:30 h and 21:30 h, to ensure arrival at the cenote before darkness deepens. The following table summarizes the most common pick‑up locations, the primary routes taken, and average travel times to the four featured cenotes. Times are based on standard traffic conditions for the month of May 2026; seasonal variations (e.g., holiday traffic in December–January) may add 10–15 minutes.

Route Characteristics and Night‑Travel Considerations

1. Highway Conditions – The Carretera Mérida‑Progreso (Federal Highway 180) is a four‑lane, paved thoroughfare with continuous lighting from km 0 to km 150. Speed limits are 90 km/h in rural sections and 70 km/h within the urban fringe. Pothole repairs completed in early 2026 have reduced vibration on the stretch between km 70 and km 95, improving passenger comfort during night travel.

2. Secondary Roads – After exiting the main highway, tours follow Ruta 184 (Cozumel‑Cuzamá) to the cenote clusters. This road is two‑lane, paved, and equipped with reflective markers. The segment approaching Kankirixche includes a short (≈2 km) gravel section that was resurfaced with compacted stone in March 2026; travel speed drops to 40 km/h for safety.

3. Traffic Peaks – Evening traffic in Mérida peaks between 19:00 h and 20:00 h, especially on Av. 60 sur and Av. México. By the scheduled pick‑up window (20:30 h–21:30 h), traffic typically eases, allowing the average travel times listed above. During the Holy Week period (late March to early April), expect an additional 10–12 minutes due to increased outbound flow from the city.

4. Safety Measures – All vehicles used for night tours are equipped with interior LED lighting, GPS tracking, and two‑way radios. Drivers receive nightly briefings on road conditions, and a secondary driver is present on routes exceeding 100 minutes to ensure driver fatigue is minimized.

5. Weather Impact – The Yucatán Peninsula experiences occasional nocturnal rainstorms from June to October. In the event of heavy rain (≥10 mm/h), travel times may increase by 15–20 minutes, and certain unpaved segments could become temporarily impassable. Operators monitor the Servicio Meteorológico Nacional feed and will notify passengers of any schedule adjustments at least one hour before departure.

Practical Tips for Passengers

• Arrival at Pick‑up – Plan to be at the designated location no later than 20 minutes before the announced departure time. Late arrivals may result in the tour proceeding without you, with a guaranteed re‑booking for the next available night.
• Luggage – Only one small bag (max 20 kg) per passenger is permitted for night tours. Larger items must be stored in the vehicle’s trunk; drivers will secure them to prevent movement on uneven road sections.
• Dress Code – Light, quick‑dry clothing is recommended. Although the vehicle interior is climate‑controlled, temperatures can drop to 18 °C after 22:00 on higher‑altitude cenotes such as Kankirixche.
• Refreshments – Bottled water and a light snack are provided on board. No additional food service is available after departure from Mérida.

By understanding the pick‑up locations, primary routes, and expected travel times, guests can confidently plan their exclusive cenote night‑swim experience, ensuring a seamless transition from the historic streets of Mérida to the luminous waters of the Yucatán’s most charming natural pools.

Required Documentation and Pre‑Tour Health Clearance Procedures

All participants in the Merida exclusive cenote night‑swim tours must complete a standardized documentation package before the reservation is confirmed. The package serves two purposes: compliance with Mexican tourism regulations and verification of the health status required for safe underwater activity after dark. Failure to provide any item within the specified timeframe will result in automatic cancellation of the reservation and forfeiture of any deposit.

• Negative Test – If the participant has not completed the vaccination series, a PCR or rapid antigen test performed no more than 24 hours before the tour is mandatory. The test result must be uploaded as a PDF.

#### b. General Health Questionnaire

All participants must complete an online health questionnaire covering:

1. Recent fever, cough, sore throat, or shortness of breath (within the past 72 hours).

2. Chronic conditions that could be aggravated by cold water immersion (e.g., uncontrolled asthma, heart disease, epilepsy).

3. Current medication that may affect swimming ability or consciousness (e.g., sedatives, antihistamines).

A “clearance” badge appears in the reservation system only after the questionnaire is submitted and reviewed. Participants reporting any of the above symptoms are automatically excluded from the night‑swim segment and offered a daytime alternative or a full refund.

#### c. Physical Fitness Confirmation

• Medical Clearance Letter – Required for participants over 60 years of age, pregnant individuals, or anyone with a known cardiovascular, respiratory, or neurological condition. The letter must be signed by a licensed physician, state the participant’s fitness for moderate‑intensity aquatic activity, and be uploaded as a PDF at least 72 hours before the tour.

4. Timing and Submission Protocol

1. Reservation Confirmation – Occurs after the core travel documents are uploaded and the liability waiver is signed.

2. Health Clearance Review – Begins immediately after the reservation confirmation; the system flags any missing or non‑compliant health items.

3. Final Approval – Issued 24 hours before the scheduled night swim, accompanied by a QR‑coded “Access Pass” that must be presented at the cenote entry gate.

All participants should allow a minimum of 48 hours for document verification and 72 hours for medical clearance processing. Late submissions will be rejected without refund, as the exclusive nature of the night‑swim tour requires strict adherence to safety protocols.

5. Special Considerations

• Allergy Disclosure – Participants with severe allergies (e.g., to insect stings or latex) must note this in the health questionnaire; a small first‑aid kit will be prepared accordingly.
• Language Requirement – All documents must be in Spanish or English. If submitted in another language, an official translation must accompany the original.
• Data Privacy – All uploaded files are encrypted and retained only for the duration of the tour plus a 30‑day post‑tour audit period, in compliance with Mexico’s Federal Law on Protection of Personal Data.

By completing the documentation and health clearance steps as outlined, participants ensure a seamless reservation experience and a safe, unforgettable night‑swim adventure in Merida’s most iconic cenotes.
