btw Royal Caribbean has cracked down more than most on bringing alchohol onto the ship when you board. We cruised Easter week and during the spring break cruising season they confiscated everything. If you had a questionable item in your locked suitcase you were called down to open your suitcase. Like those who put it in mouthwash bottles.
If it was in its original container you got it back at the end of the cruise.
No bottles are allowed on RCL currently per ther policy. They state they can deny you boarding. There was a rumor of a college kid who tried to bring like a dozen bottles of vodka who was denied boarding. I think it has to be an extreme case before they would stop you from boarding or someone who argues about it?
So Carnival allowing a bottle of wine per pax to me is wonderfull and better than no bottles. lol
