Sailed on Royal Caribean out of Houston in 2010 and they 'found' a suncream bottle in our case - which, contained suncream - although they didn't check inside it ;} so our case was sent (along with hundreds of others) to the conference room in the lower decks and we had to go identify, open, collect it.
On Celebrity you can takje 2 bottles per stateroom at embarkation PLUS according to an admin on Cruise Critic - if you go on an approved tour during the Wine Cruises, you can bring an additional 2 bottles on each time ;}
Celebrity Constellation - Sep 19th Wine Cruise ex Southampton - ANYONE ELSE ON THIS ?
