I have used this site multiple times over the past five years, with very good results as long as I have ony booked hotels that are 3 stars or above - there is an enormous decrease in quality beteween a 3 star and a 2.5 star. Also be warned that although they tell you the general location before you book, those locations tend to be very large, and the likelihood is that the hotel will be in the less attractive part of the area - after all, that is why they need to use this service to full their rooms. But if you are willing to accept this limitation, the rates are generally much lower than the ones that I have found on comparable sites. Also a hint - if you are booking somewhere (like London) where there are a lot of hotels, you can often figure out which one is listed on hotwire by comparing the features to those listed on hotels.com, since the two sites use the same categories for features.
