Once you are ready to submit a new booking, follow the same process used for the original booking.
The Checkout page will display a section named “Promotional Code and Boating Credits” and a field named “Boating credits”. Your credits balance will be shown here. Click “Apply” to use the available credits to pay for the booking.
Please note that credit card details are still required in case there is any balance left or a subsequent refundable security deposit that may be needed.
