OK, so we're going on the 11-Night Holiday Cruise and I just purchased two $25 gift cards to give to our girls on Christmas morning in their stockings. Will they be able to take the gift cards to guest services and have that $ put onto their KTTW cards so they can then spend the $ in the gift shops? I'd hate to give them the G/Cs and then them not to be able to use them on the ship. If they can't, we'll give them the G/Cs in the box that we are giving to the girls @ Thanksgiving to let them know we're going on the cruise to begin with. But I'd really rather put the G/Cs into their stockings on Christmas AM. TIA for any advice!
