Only one bottle of wine at the start of the trip (though of course many people bringing waterbottles on are full of vodka, not sure if you can still sneal those on or not)

Guests are prohibited from bringing alcoholic beverages onboard. However, guests 21 years of age and older only may bring one bottle (750ml) of wine or champagne, per person, on board only during embarkation at the beginning of the cruise. A $10 corkage fee per bottle will be charged should you wish to consume this wine in the main dining room; $14 corkage fee per bottle in the Supper Club. Guests may bring a small quantity of non-alcoholic beverages. All prohibited alcohol, additional quantities of wine/champagne or excessive quantities of non-alcoholic beverages will be confiscated and discarded without compensation.
