Imperial Palace is a soft game. Weekend you will most likely find something soft anywhere. MGM used to be nice, but not sure what the .5/1.00 NL game has done to the 1/2 game.
Golden Nugget has no max 1/2 buy in. Bellagio is always good, but don't be upset when you are treated like crap from the room.
I've done quite well at Harrah's overnight. It's hard to say what is best because that probably changes every night/weekend. Don't tie yourself to one room and be open to move to different rooms until you find the one that suits you best.
Bellagio/Venetian/MGM will have the most table running.
