Excuse my ignorance but Harrahs seems to be around the same price as the Imperial Palace ($56 a night)......as much as I like to THINK I'm not a snob, I hate crappy hotel rooms

On a scale of 1-10 with IP being around a 3 and the Venetian around an 8, what would Harrahs be?
I was just looking and it says that the Sands Expo Center is adjacent to Harrahs - isn't that where the convention is?
