Planning our trip (probably October) and have decided that Downtown, for various reasons, would suit us just fine. (We'll do "daytrips" to the Strip.) I'm a smoker, Ace is a non-. And in spite of him living with my smoking for 40 years (though I smoke outside the house nowadays), there have been times at various local casinos that the "smokiness" has bothered him. The casino itself, not our room, is what I'm talking about. So wondering: are the older downtown casinos really noticeably smokier than those on the strip? I imagine the newer strip casinos have more state-of-the-art air filtration systems (or whatever it is they do), but I'd also imagine that ALL the casinos do their best at the air filtration. Is this something I should maybe consider in my decision on where to stay? I'm leaning toward Downtown in general, and the Cal in particular, for our trip. Thanks!
