As you book online you will assure your seat on the boat for the excursion you have chosen. After completing the checkout of your booking you will receive an E-Mail with all your reservation informations. The first E-Mail will be the booking received statement and a couple minutes later you will receive another E-Mail with the booking completed statement. The day in which the excursion takes place remember to bring the E-Mail with you and show it to a staff member. That’s it, there is no need for more! And if you lose the Booking Confirmation E-Mail you can give us your name and surname or even the e-mail which whom you have booked the activity and we will be able to find your transaction on our database so you will be able to make your excursion anyway. It may be necessary to show an ID to confirm your reservation without the E-Mail, nothing more.
