We cruised Jan 13th and took a 12 pack of coke, potato chips, and a few other snacks. You really don't need to pack a lot of snacks as they have individual bags of chips at Pluto's, where you get your hamburgers and hotdogs. You can also order room service 24 hours a day. They have cheese and crackers, pizza, hamburger's, chicken fingers, sandwiches, cookies and other things you can order. You also can not bring opened food back into the U.S. When you did disembark you will be fined if caught bringing food back. Other than beverages you probably won't even consume the snacks you bring, we didn't.
