On most Royal Caribbean ships in 2026, smoking is permitted in designated areas of the Casino Royale, provided you are actively playing. However, the cruise line has moved toward a "split" model to satisfy all guests: there is typically a clearly marked "Non-Smoking" section of the casino that features a separate ventilation system. This policy does not apply to all ships; for example, on cruises departing from China or specific European ports, smoking policies may be stricter. Outside of the casino, smoking (including e-cigarettes and vapes) is strictly prohibited in all staterooms, on all private balconies, and in all interior public spaces like theaters and restaurants. Violating the "no-smoking in cabin" rule triggers a mandatory $250 cleaning fee. For 2026 travelers, it's worth noting that "Oasis-class" ships have some of the most advanced "smoke-scrubbing" technology in their casinos, but for those who are highly sensitive to smoke, the "Solarium" or "Starboard-side" outdoor decks remain the only other sanctioned smoking zones away from the gaming floor.
