All reservations must be warranted by means of a credit card. When making your reservation the system will automatically charge the total amount and will give you the confirmation number. The confirmation of the reservation will be subject to acceptance of the credit card included in the request form. Aventuras Arenal does not confirm your reservation when your credit card presents some inconvenience, or is turned down. (Not accepted). In case of no room or tour space, a full refund will be send to the client. All reservations will be confirmed by email.
