On a TUI (Marella) cruise ship, smoking is strictly prohibited in all indoor areas, including all staterooms, suites, and private balconies. This policy is strictly enforced to ensure fire safety and the comfort of all passengers. If you are caught smoking in your cabin or on your balcony, you will be subject to a significant "cleaning fee" (typically around £200) and potential removal from the ship. However, TUI does provide designated smoking areas on the open decks of their ships. These areas are clearly marked and usually include ash trays; they are typically located on one side of a specific deck (often the pool deck or a lower promenade deck). This rule applies to traditional cigarettes as well as e-cigarettes and vapes, which must also only be used in these designated outdoor zones. For those who are sensitive to smoke, the vast majority of the ship remains a smoke-free environment. In 2026, Marella Cruises continues to prioritize a "fresh air" experience while accommodating smokers in controlled, well-ventilated outdoor sections of the vessel.
