Unique scent is addictive I've visited many casinos and as far as air quality hands down the Luxor Hotel hit the Jackpot. Don't believe stop in for a visit sniff the air and you will see. Why is this important? Smokers are everywhere premium air quality is important. Rooms are nice no super frills but very nice all the same no hiccups ever. Is noise a concern no worries I slept like a baby. I spend very little time in my room while in Vegas but still when I do I want it nice.
