Must be nice... all four casinos in CA I've been in reeked of stale cigarette smoke.
The first casino I ever went to was Morongo, which is off the 10 freeway on the way to Palm Springs. It runs ads ALL THE TIME, and it looks wonderful. Yeah, well...the smoke was so thick in there you'd need a machete to cut through it. Their "non-smoking room" was a small, pathetic room with an awful selection of older slot machines, no staff at all, and smoke POURING into it through the ventilation system--which it shared with the main part of the casino. I only lasted about an hour and we had to leave. I had to use my rescue inhaler. It was miserable.
In contrast, as I've mentioned, Pechanga is wonderful. There's an entire side of the casino that's non-smoking, and it has all the same new, fancy slot machines as the rest of the casino, plus it's heavily staffed and everything. There's no difference between it and the smoking part except for the smoke!
For those who don't know, and may be wondering why smoking is even allowed in casinos here, since California is the non-smoking section of the US and everything, it's this: They're on Indian land. The Native Americans are not bound by California law on their tribal land, so they can allow smoking or not, it's up to them.
I never gamble... never have any spare cash to throw away like that.
I'd never been to a casino in my life...until I moved back home to CA and my mom got me hooked.

But I know it's not a good option for some people.
