I think it's interesting that this discussion is still going on! I was playing "devil's advocate" when I posted this way
back in 2005! At that point I had many
friends and relatives who smoked. Now, I don't think I know anyone
We were on the Carnival Conquest recently and enjoyed the Casino Bar (Impressions). Smoking is allowed in the Casino, but I never smelled any smoke. It seems that the ventilation is working very well.
