We put a bottle of scotch (for him) and a bottle of vodka (for me) in bubble wrap and put it in our checked luggage. Got there just fine. Do NOT try to put it in carry on. They check bags as you are going on the ship just like at airports. They will confiscate it. I put a large bottle of club soda in the carry on (to mix with the good stuff) and that was OK. We saw numerous people with small coolers roll on board - I have to assume they had soft drinks in there. I was told they will let you take soft drinks and bottled water on in moderation.
Have a great cruise!!
