Bid the above dates from $100 to $110 with no success at 4 and 3 1/2 stars. The Priceline Negotiator iPhone app lists recent successfull for this area of $120 for 4 stars. I'm guessing that these are often weekend rates as they seemed to go down on Friday and that weekday rates are going to be a lot higher. I'm willing to wait until closer in to book a room. I have even showed up in Vegas for a weekend without a room reservation and just used PRICELINE to find a room when I was ready to check in for the night.
