I just traveled on a 7 Night Western Mediterranean Cruise, Navigator Of The Seas,Royal Caribbean on August 1st, 2010 departing Civitavecchia (Rome), Italy
I was remiss, in advance to check with the cruise line & my travel agent about their smoking policy. I had cruised the last 3 summers in Europe on both Celebrity (sister ship) and Holland America. Smoking was allowed on those cruises, in public areas, in designated smoking sections permitted outdoors on only one side of the ship.
If I knew in advance that much of the aft of the ship, including the piano bar, lounges, casino, pool and more locations all allowed smoking, I never would have taken the cruise. The options to use the ships facilities for a non smoker were limited. Much of the fun, festive activities available after the show were inundated with smoke. It was uncomfortable & effected my enjoyment.
