The new train system runs behind the hotels on the east side of the strip. That being said, please take a look at the Monorail map. All the big hotels have smoke-free rooms and smoke-free gambling tables. And whatever the MGM Grand was pumping into their system to eliminate the smoke smell gave me an immediate headache.īut I think you will be suprised at how little smoke you will run into these days. One issue I had, though, is that I am also sensitive to some chemicals/smells. I am very allergic to cigarette smoke and I was in several casinos last year that were fine. Well, I've found many of the hotels along the strip have greatly improved on the smoking thing.
