We got off the Lengend last week and it was the smelliest cruise we have been on. The Casino was the least used one that I have seen but when we would walk through every table and bar stool was filled with smokers in front of the Casino bar. Since that is a designated smoking area they can smoke and if I don't like it I don't have to stay or go through there. We completely skipped gambling on this cruise for the first time as it was so bad with smoke and the friends and family we traveled with felt them same as some of them spent about 10 minutes in the Casino and then just gave up. The smokers who smoke in the designated areas I understand but our group occupied several balconies on both sides of the ships and almost all of us smelled cigarette smoke on the balconies at times. In the past if we saw someone smoking on the balcony we would simple ask them not to as it isn't allowed and we usually get a "sorry" and they don't do it again. Only once did we have someone next door to us get extremely mad cuss us out and then they started chain smoking on their balcony my wife just went in and called GS and in a few minutes someone knocked on their door and they all went into the cabin and we never saw them on the balcony the rest of the cruise. This time we could never see who was doing it. We also while walking down the hall passed rooms that apparently they were smoking in as the hallway smelled of smoke a few times.
