Yes Mailman has it right. Go to the informed bidders website at www.biddingfortravel.com and do your research BEFORE bidding on Priceline.com. Biddingfortravel takes some of the guesswork out by:

Listing hotels, by stars, by area that have been won on Priceline
Members post their winning bids with stars, dates and amounts paid.
You can see history of what hotels are coming up in an area by star rating.

I have found the moderators there to be militant and would caution you on posting there.
