Don't try to sneak it onto the boat, been there, tried that, didn't work. I did find out that you can call Carnival and purchase liquor and have it waiting in your room. Unfortunately I didn't find that out until recently. I could of saved A LOT of money if we would of done that, buckets of beer add up real quick! I think they are talking mostly about bottles of rum, vodka, etc. The prices are quite affordable!!!
