There are no cigar rooms on the Grand, and I did note signs in the casino that said "cigarettes only". I do not recall seeing these signs in the lounges, but I also didn't see anyone smoking cigars in the lounges. Many areas of the ship are designated "no smoking". The daily newsletter listed a cigar social on one afternoon at the outside bar behind the Horizon Court. I went to this (I smoke cigars too) and there were maybe 10 people sitting around puffing and talking - but this area of the ship had cigar smokers every day. I guess it is the designated cigar area.
