If you have purchased an Island Pass for your stay in Galveston, you will input the confirmation code when you reach the payment section of the registration process. Island Pass is an option in the voucher drop-down menu. Please note that if every member of your party has their own Island Pass you will have to input the confirmation code from each pass and click submit in order for the discount to take effect. You may still have to use a credit card to pay for the registration fee.
