If you don't care exactly which hotel you end up at, it could end up being a good deal. There are sites that list which hotel you could end up with if you bid. I'm not sure if you can put the site on this board, but the hotels listed as 3.5 star in Anaheim South are: Crowne Plaza Resort Anaheim-Garden Grove, Embassy Suites, Hilton, Hilton Suites, Marriot Suites, Red Lion Inn and Sheraton Garden Grove Anaheim South. If you list the amenities the hotel has, it can help narrow down which hotel it is.
Just based on the price and what is normally "won" in that area I'm going to guess it's either the Crown Plaza or Red Lion.
