I'm going to Baltimore for a convention and the prices are a bit higher than usual. I'm actually staying for two nights and I got greedy and paid the price. Word of caution: If you see a price on the Express Deals and you decide to try and bid and get something lower, there is a chance that the Express Deal will go up 10 to 20%. It has happened to me twice in the past month and maybe I'll learn my lesson. Here's how this one unfolded: I searched on Express Deals from 9/18 to 9/20, and a 3 1/2 star, which I deciphered to be the Sheraton, showed up for $110 per night (list price $235). However, when I searched on 9/18 to 9/19, it was $87 (list price $240); and 9/19 to 9/20 was also $87 (list price $230). Now the greedy part, I bid on 9/18 to 9/19 starting at $50 and with free re-bids, worked my way up to $85. When $85 was denied, I decided to go back to Express Deals and buy the room for $87. Except for one small problem, the price was now $110. I then went to the 9/19 to 9/20 Express Deals and saw the price was still $87. I bought the room and then tried to add one earlier day. It gave me the option of $110. Which brings me to this bid. I waited a day, came back to 9/18 to 9/19, and saw the Express Deal was still $110. Would the price go up again if I tried bidding? One way to find out. I started at $85 and then using free re-bids won the room for $95. At the end of the day, I got the first night for $95 (list $240) by bidding and the second night for $87 (list $230) by using Express Deals. Moral of the story -- it may not make sense to the veteran Priceline bidder, but if you see a PRICELINE EXPRESS Deal for 60% off, don't get greedy because it might cheaper than bidding.
