Hi everyone! I heard that you can use gift cards in place of your credit card for your on board account. To whom do I give these cards to when we arrive on the ship? I am also planning on giving them my credit card number, but have slowly been accumulating gift cards. Do they use the gift cards first and then go on to the credit card? I am just a little confused seeing as how this is our first time cruising. Thanks so much for any info you can give!
