markone,
I did Priceline two times, once we were lucky enough to get the Wyndham Palace for $55.00 per night bidding for a 4 star-Disney area. Once we got the Rosen Centre for $35.00 per night bidding for a 3 star-Universal area. Remember, it's NON REFUNDABLE-NON CHANGEABLE, so definitely read all you can about Priceline before you bid. Another tip, don't get discouraged if your first bid is not accepted, I go up in usually $5.00 increments, at the Wyndham I bid $50.00, they didn't accept it, so then I bid $55.00 and they accepted it!
Good Luck!
Leah
