I used to sneek liquor on Sov. Of the Seas. I found out it is cheaper to buy from the ship liquor store after the ship pulls out. There is a 11.00 set up fee to take it right to your room. Absolute Vodka 9.95 a bottle. It was still cheaper than orlando liquor store. As for carrying around your own liquor, they do not car. The only suggestion I have, is bring a big mug to put it in. It gets to be a pain walking down to the cabin each time I wanted a drink.
Can't wait till June 18,06. RCCL to Alaska
