No, you cannot smoke on any stateroom balcony on a Carnival Cruise Line ship. As of 2026, Carnival maintains a strict no-smoking policy in all guest accommodations, which includes the interior of the room as well as the private balcony. This ban applies to all forms of smoking, including traditional cigarettes, cigars, pipes, and electronic cigarettes (vapes). Smoking on a balcony is considered a major fire hazard at sea, where a discarded butt could easily be blown back into a neighboring cabin or a lower deck. If a guest is caught smoking on their balcony, they are typically assessed a $500 cleaning and safety fee on their "Sail & Sign" account, and persistent violators may be asked to disembark at the next port without a refund. For those who do smoke, Carnival provides clearly marked designated smoking areas on specific outdoor decks (usually on the starboard side) and within specific sections of the casino for active players. Always check the ship’s map or the Carnival HUB app for the exact locations, as they can vary slightly by ship class.
