Yes, you can. When you submit a booking for a boat rental priced over $500, you will have the option to choose if you want to use your Boating credits or not. If you choose to use it, then Click on “Use credit” link at checkout. If the boat rental price is higher than available credit, then all your Boating credits will be used and the balance must be paid by credit card. If the boat rental price price is lower than available credit, then the needed credit will be used. Your account will then show the remaining balance.
