NEW UPDATE (and another 'win'): Same dates, same amenities: Yesterday I booked an additional room for Friday, July 2nd - price $87. (total with tax recovery and fees = $104.43). As expected, got Westin Stonebriar (listed in Plano, TX on Hotwire). Oops - made a mistake - I needed TWO nights. When I went back in to book the second night (July 3rd), the HOTWIRE rate went to $102. ($ 121.19 with fees). I waited a couple of hours because on Sunday the rate dropped back down to $87. a short time later. Yesterday the HOTWIRE rate remained at $102. and is still $102. today. We really needed the room but before booking it I checked out the hotel website through www.spg.com and found the Westin Stonebriar there for $99. (total with taxes = $ 111.87). Booked that second night through the hotel site and saved the extra $10. Tips: When you see a good rate, be sure how many nights you want and get the rate for all nights while you can. I mistakenly thought we already had the second room for Saturday and having to rebook when the HOTWIRE rate changed would have cost an additional $17/nt. If you see a rate go up, it may be because someone has recently booked a room or rooms and the rate MAY drop back down a few hours later or the following day. Don't count on it if you really need the room, but if you are flexible and okay with the higher rate, it might be worth looking at the site a little later to see if there is a drop. Risk is another increase or no availability, but reading the posts here and using the links provided can help you make the best possible judgment call. Sometimes the HOTWIRE rate will drop as you get closer to your stay - I've seen one go from $79. a week before my trip to $69. the day before and drop to $59. after noon on the day I wanted to stay. This wait and see strategy is only a good idea if you have a high degree of flexibility and are willing to risk a different hotel/star rating or higher price - but it can pay off when you can handle the risk and don't mind not knowing where you're going to stay until a few hours beforehand. I used this two years ago and the $20./night + fees difference over the 4 nights I stayed in Dallas saved over $100. (Dallas Galleria area - June 2008 - Sheraton). One more win for 07/02/10 4* Westin Stonebriar Plano/Frisco, TX $ 87.
