Aria/Wynn/Venetian, **** everything else. Bellagio if you go to Aria and games are dead/not running (only a relevant worry 2-3 hrs of the morning).
Best quality rooms, best comp rates, games with people willing to lose more than 50 bucks, why am I still listing things, best outlets to spend said comps on, Buehler?, most affluent recreationals in the hotel area, opening raises consistently >$6 which you cannot guarantee elsewhere, yada yada yada
Gl have fun
