All Inclusive Beverage Package: There may be a beverage packages are purchased when on the first day of the cruise, aboard ship. Normally, if one person in you cabin purchases it, everyone in your cabin must purchase it. In the past, most hashers BYOB on board even though its contrary to the ship's policy, as its not well enforced. You just can't be too obvious, or put all your eggs in one basket. Officially though, we cannot give you permission or recommend you do this. Unofficially, its a heck of a good idea if you can get away with it (most people do). Its not against the law, its just against the cruise lines rules as they want you to buy their booze. So do as you will. Contact me personally for more info or advise, if needed.
