If you book through their web site you can get some very good deals. So long as you were not close to a smoker, it was not a problem. While we were there (on a tuesday and wednesday evening) there was some smokiness, but overall it was very tolerable. First, mid-week the casino was OK, but on the weekends I could imagine it getting a little smokey so it is something to consider if you are sensitive to smoke. Overall, it is a very nice hotel and casino but there are a few things to consider. We had tickets for a concert (James Taylor, who was fantastic) at nearby Valley View Casino which does not have a hotel (although there is construction going on that could be a new hotel).
We recently stayed at Rincon for a little mid-week get away.
