Just wondering....what were the other 4-6 cruises you have been on where the ships were non-smoking or even the casinos? When I sailed the Caribbean Princess last April, there were Non-Smoking day's in the casino and on the off day's, smoking was only permitted on the Starboard side of the casino. In the case of your "Tip", if you are a non-smoker, and smoking bothers you as much as you seem to communicate, you may not want to sail on any major cruise line as they ALL permit smoking in designated areas.

I have been on lots of ships....... I will have to agree with the OP the lay out on 5th deck is poor for the non-smokers. I was on the Glory and did as little as possible on the 5th deck. The smell of smoke from the open casino even got into the piano bar that had doors to it, same with the comedy club. There was a good band playing in the walk way but we did not stay because of the smoke. I also think do to demographics of guest Carnival gets a higher % of smokers then other cruise lines.
