Just got back from the Caribbean Princess on Saturday. We carried lots of liquor in our luggage, carried wine and champagne with us onboard. We also took 2 cases of water, just put a princess luggage tag on the packs, and it was delivered to our room!! Just do pack a corkscrew if you plan to have wine in your cabin. Take an insulated cup, or a coolie cup with you so your drinks will stay cold!! Also, they only have horrible iced tea, no lemonade or punch, so keep that in mind and pack accordingly!
