You need to cancel your reservation with Rez Adventures at least 24 Hours before the date of your reservation, or if there is inclement weather with precipitation at the beginning of your reservation then we will not charge you for $50.00. The $50.00 is a charge for having the boat gassed up and on the dock that we do not charge so long as you cancel your reservation so just let us know before hand and we will not charge you. This 1 dollar charge is to confirm that we have a authorized card on file to hold the reservation.
