if your bets are as big as your condoms, they may put up a sign. haha!

i usually ask when i sit down if we can please make it a non smoking table. sometimes they do, sometimes they dont.

the Orleans has non smoking areas in the casino.

I know that some are now offering non smoking sections for gaming. Here is a bit of information about them.

Palazzo had non smoking areas, signs were posted.

On a recent trip I did notice that the Cosmo had less smokers than other places.

I smelled more smoke (cigarette type) at Wynn casino

Their rooms are non-smoking and I've noticed that in the casino there's very little smoking going on.
Hope this helps.
