Cruise passengers back smoking ban Non-smokers object to the smell of smoke invading their private space, but there are also cleaning costs and safety issues. One person died when fire, believed caused by a lit cigarette, broke out on a balcony on Star Princess in 2006. Do you think smoking should be banned on cruise ship balconies? Royal Caribbean International, Cunard and P&O Cruises are following suit, while Seabourn, one of the last lines to allow passengers to light up in cabins, is outlawing that practice next year. Passengers will also no longer be allowed to smoke on the French balconies on Seabourn Legend, Pride and Spirit. German line Hapag-Lloyd Cruises and Italian companies Costa and MSC allow smoking in designated lounges. Hapag-Lloyd passengers can still smoke on balconies.
