  • The present Terms and Conditions apply to this contract, the content of which the customer accepts implicitly with the first payment (deposit or full payment) or explicitly with the completion of the registration form.

  • Exception: In case of travel arrangements or individual services of other organizers, we act as an intermediary and their respective contract conditions apply.

Naturally, in such a case, the client will be excluded from all activities.

Booking confirmation

Immediately after receiving the deposit, AQUAERIUS will send the client a booking confirmation as well as any additional information, course documents, itineraries etc.


  • Our price quotations always include the relevant currency.

  • In general, our prices are very consistent - however, we reserve the right to adjust our prices at any time and without prior notice and justification.

  • In the event of a subsequent price change, we undertake to inform the affected customers immediately.

  • With the exception of travel arrangements, price increases from the 14th day until the start of the activity are ineffective, i.e. will be covered by us.

  • Tips are generally not included in our prices.

  • The regular prices are always applicable from Puerto Morelos. In principle, no discounts are granted on vacant rides.

Cancellation policy

In principle, the customer can cancel the contract at any time before the start of the booked activity. If he does so, AQUAERIUS can claim compensation for the arrangements, expenses and efforts. These costs and fees will be charged directly to the client. The date of receipt of the written cancellation notice by AQUAERIUS is decisive. Cancellation fees must be paid within one week.

  • Until the 14th day before the activity a cancellation is free of charge (excl. possible refund fees).

  • From the 14th to the 7th day a compensation of 20% of the total amount, but at least USD 50, is due.

  • From the 7th to the 2nd day this is 40%, but at least USD 60.

  • From the day before the activity as well as in case of no-show at the activity, a compensation of 60%, but at least USD 70 of the total amount is due.

  • Exception: For travel arrangements, individual regulations apply, which are specified in more detail on the offer.


All insurances are strictly the responsibility of the participant.

Cancellation by organizer

AQUAERIUS can terminate the contract without notice and claim the full service price for the following reasons, among others:

  • If the customer, for behavioral reasons, disturbs the activity persistently and/or harasses other participants.
