(The exception is Costa Cruises, which does allow smoking on outdoor balconies.) Can you light up on deck? Typically yes, but only in designated areas. Are you allowed to smoke on cruise ship balconies? Definitely not it's a fire hazard. What about cruise ship cabins? Never, unless you are vaping - and only a handful of ships permit that. Cruise ship smoking policies vary by cruise line, but typically smoking is not allowed, except in a few designated onboard areas.Ĭan you smoke in cruise ship restaurants? No.
