We were on Sea Princess at Christmas. You are allowed to take on board Beer and Wine. I also took a bottle of Vodka on board at one of the Ports and nobody stopped us, although they do say they will take if of you and return to you at the end of the cruise. I felt they were very relaxed about what you took on board.
