I would say to avoid the former smoking rooms at all costs. We just had 2 former smoking rooms at Coronado, and they were horrible. I even asked at checkin, if they were former smoking rooms, and was told "I don't know." Yeah, right! LOL. We asked to be moved as soon as we got into them, and they moved us immediately. The CM said everyone who got these rooms asked to be moved. (do not allow them to come spray, or use electronic air cleaners, they do not help that much).
We were moved, all went well after that, but they really need to strip those rooms down, replace everything, repaint, etc.
