As of 2026, Carnival Cruise Line prohibits guests from bringing any bottled water (or any other beverages in plastic bottles) onto the ship. This policy was implemented to streamline the security screening process and reduce plastic waste. If you wish to have bottled water in your stateroom, you must purchase it through the cruise line—either pre-ordering a case of water for delivery to your cabin via "The Fun Shops" or buying individual bottles at the ship's bars. However, Carnival does allow guests to bring a small quantity of non-alcoholic beverages (soda, sparkling water, or juice) as long as they are in sealed cans or cartons (max 12 oz each) and are carried on in your hand luggage (limit of 12 per person). In 2026, passengers with specific medical needs requiring distilled water for CPAP machines or baby formula can contact Carnival's "Special Needs" department in advance to bring the necessary supplies, but for general consumption, the "no plastic bottles" rule is strictly enforced at all embarkation ports.
