Carnival tried for years with the Paradise. It just wasn't making enough profit. The revenues from the casino and bars were not inline with the smoking ships. Don't you think that if there was any way this could have worked, Carnival would have found it? It comes down to non-smokers not spending enough cash on board. Sorry, but I think that there will not be a non-smoking ship for a while. They may limit where you can smoke, but they will have to be careful about it. I was on Holland America in Nov. 06, they made the casino non-smoking from like 7:00 pm until 10:00 pm. During this time, I swear, the casino was empty!! At 10:00 pm, it got busy. Just as soon as the no smoking sign came down, it was packed.
