Alcohol consumption while on a cruise is a common question. Cruise lines vary in their policies regarding alcohol, but most allow passengers to bring a limited amount of alcohol on board for personal consumption. The amount of alcohol that passengers are allowed to bring on board varies by cruise line, so it's important to check with the cruise line before packing.
Typically, passengers are allowed to bring one bottle of wine or champagne and one bottle of spirits on board. Some cruise lines also allow passengers to bring a limited amount of beer on board. It's important to note that all alcohol must be packed in sealed containers and must be declared to customs upon arrival at the cruise port.
