Our online gift certificates are redeemable towards any reservation booking for all of our available public cruises. You may redeem these online, by mail or in person upon successfully booking your cruise. After submitting your billing information below along with a dollar amount, you will be presented with a printable gift certificate containing a unique ID number. This number may be entered into our online order-form for public cruise reservations, crediting the amount of the certificate towards your purchase. Please hold onto this certificate as The Detroit Princess does not issue exchanges or refunds after a ticket or gift certificate has been purchased or for lost, stolen, damaged or destroyed tickets or certificates.
