I've never used Expedia, but have used most of the others. I could be wrong, but I prefer hotels.com for hotels, as they seem to go into more detail than others. An example would be that a hotel normally offers a free breakfast (continental or otherwise), but not to hotel.com guests. We stayed at a simply amazing Radisson last summer for one-fourth of the price, and for that, we could afford our own breakfast!

If I'm about to book through one of these services, I always go to the hotel's real website, and compare the prices & perks. It's well worth the time! Also, be sure to read former guests' comments on the place - there are a lot of deal breakers aomng them!
