I have always taken wine in the small bottles (4 packs) in my carry -on luggage. No one has ever said a thing. Though they have there restrictions in the brochures, I don't think they really can say anything to you when you are boarding in a U.S. port (it's not much different then going into to your hotel room). I've never tried to take anything on at a non-American port and have noticed people giving over there booze when entering the ship. I like the idea of a box of wine in my checked luggage. It won't leak, and will probably last the week. Thanks for the suggestion!!
