Well, I did spend a vacation on Nassau one year. And the waters were gorgeous. I guess a cruise down around Florida and over to Cancun, St. Thomas and the islands would be ok. But I don't think I would trust a cruise to Alaska now.
Smoke in the cabin? Only? Gee, they are all heart. LOL!
Cruise ships are really tolerant of smokers. The only restrictions on smoking are in the dining areas, the theaters, library, etc......in other words, same as in land hotels and restaurants in most states.
