Most major cruise lines have strict "no-liquor" policies for checked or carry-on luggage in 2026. Typically, you are prohibited from bringing beer or hard liquor onto the ship; if found during the X-ray screening of your suitcases, these items will be confiscated and either disposed of or held until the end of the voyage. However, many lines (like Royal Caribbean, Celebrity, and Disney) allow each adult of legal drinking age to bring one 750ml bottle of wine or champagne in their carry-on bag during embarkation. This bottle must be sealed and is often subject to a "corkage fee" if you choose to drink it in a dining room rather than your cabin. It is a common mistake to pack alcohol in checked bags, but cruise security is highly adept at spotting "smuggled" bottles using advanced scanning technology. If you purchase alcohol at a port of call, the ship’s security will store it for you and return it on the final night of the cruise so you can take it home.
