Access to the hotel rooms requires your room key - a nice security feature. To their benefit, the common walk-ways and surrounding restaurants and bars are non-smoking, so if you're there for anything but gambling, the odor is much less noticeable. As such, there's an ever-present odor of smoke that you can't escape. There are small 'non-smoking' sections on the casino floor, but really don't offer a smoke free environment. The casino floor, for all intents and purposes, is a smoker's paradise.
It's a very nice casino/resort that should qualify for at least a 'Very Good' rating, except.
