Policies & Terms
Policies & Terms
Clarity is part of good hospitality. This page gathers the policies shared by both brands — Mercury Cruise (private river cruises) and Mercury GT (jet ski rental) — with each brand's specific terms clearly labelled below, so you can book with complete peace of mind.
Last updated: July 2026
Weather policy (Cruise & GT alike)
We check conditions every morning before your travel date. This policy applies equally to Mercury Cruise voyages and Mercury GT rides.
Ordinary rain doesn't affect your trip — the Cruise boats are fully covered, and GT rides continue as normal.
Only in the event of a genuine thunderstorm (not light rain) will our team contact you before departure, and you choose freely between a free reschedule or a full refund — no cost either way.
Cancellation & rescheduling
Free, unlimited rescheduling if you notify us at least 24 hours before departure via LINE — applies to both Cruise and GT.
Cancel with a refund request 48 hours or more before departure: 100% refund.
Cancel within 24–48 hours of departure: 50% refund, with the remaining 50% held as credit toward a future booking (no expiry).
Cancel within 24 hours, or no-show: non-refundable, since the crew, captain/pilot, and fuel have already been committed for you.
Late arrival: please reach the pier/dock at least 15 minutes before departure. Missing a departed slot is treated as a within-24-hour cancellation.
Refunds
Refunds approved under the policy above are returned to the original payment method you used to book.
Typical timing: usually within a few business days, depending on your bank or card provider.
Any questions about a refund's status? Message us on LINE with your booking reference and we'll help right away.
Mercury Cruise — safety, deposit & payment
Mercury Cruise is a private full-boat charter, seating up to 12 guests, with a captain and crew looking after you throughout. The terms below cover this brand's safety and payment specifics.
Safety & insurance
- Standard life jackets for every seat, in all sizes for children and adults.
- Experienced captains and crew who know the Ayutthaya stretch of the Chao Phraya intimately.
- Every boat inspected before each departure.
- Passenger insurance covering the full journey.
Deposit & payment
- Reserve your date with a 50% deposit; the remaining balance is due before departure — the system reminds you automatically via LINE and email.
- If you cancel under the terms in "Cancellation & rescheduling" above, your deposit is refunded at the same rate.
Mercury GT — rider eligibility, deposit & payment
Mercury GT is access to impeccably prepared performance watercraft — freedom on the water, safely. Each jet ski seats up to 2 (rider plus one passenger). The terms below are here to look after both you and the craft.
Rider eligibility, safety & waiver
- Riders must be 18 or older and must be the registered renter.
- A signed waiver is required before boarding, via a link sent by email/LINE after booking — takes just a couple of minutes on your phone.
- A pre-departure safety briefing is mandatory — our team walks you through the craft and the route before you head out.
- Wear a life jacket and the engine safety lanyard at all times while riding.
- On-water supervision accompanies your ride, ready to assist whenever you need it.
- Never ride under the influence of alcohol or drugs.
Security deposit & damage
- Security deposit: collected separately from the rental fee at pickup, refunded in full immediately after the craft is returned safely and complete — contact us for the current amount.
- Insurance coverage: damage cover is provided; please ask our team about the details and renter excess before your rental.
- The renter is responsible for damage caused by misuse or breaking the rules, fines or damages arising from breaking the law, and loss of equipment provided with the craft.
- Ride within the briefing and the usage rules and your deposit is returned in full, as standard.
Payment
- Pay the rental in full online at booking — nothing extra to pay on arrival (aside from the security deposit above).
Payment methods
Pay online securely through Xendit, a trusted payments provider — used across both Mercury Cruise and Mercury GT.
PromptPay and credit/debit card are supported.
Your booking is confirmed automatically once payment completes, and we'll send your meeting details.
