HotCarl, the $10K buy-in is only for the Main Event (i.e., the largest, most prestigious poker tournament in the WSOP and, well, the world). Yet, during the WSOP - which spans several days - there are many other tournaments that are held (e.g., Omaha, Razz, pot-limit Hold Em), and those have lower buy-ins (though they still tend to be pricey).
Supplicium, good luck. What tourneys are you planning on entering?
Trowa, the Venetian has non-smoking floors, if I'm not mistaken, and I think the Palms has non-smoking floors available, but it's not on the Strip proper.
