I'm a long time veteran using Hotwire jointly with Betterbidding.com I also have used Pricelines name your own price bid system which also works with Betterbidding.Travelocity's secret hotels system is pretty new and there isn't a site like Betterbidding for it that I can see but I'm probably going to try it on my next visit as Priceline kinda let me down on my last visit,they supposedly upgraded me from a 2.5 star to a 3 star,however the 2.5 star hotel in that area I had gotten it before and is vastly superior to the supposed 3 star hotel they upgraded me to.Hotwire lately also hasn't had some of the hotels I used to book very often.Whenever I have friends or family ask me where I stay and how I book my rooms since I go often I tell them about Hotwire and Priceline but I always explain that even though I've gotten many good hotels, sometimes $150-$200+ rooms for $25-$50 there have been a few times you don't get the hotel you were expecting or one time the hotel only could give me a room with one bed,I always make sure to explain how it works and if they're not comfortable with it don't use it.For example I had a family member stay at the same exact 2.5 star hotel I mentioned early,very good hotel,good location free breakfast,they booked traditionally and paid $85 which they considered good,I stayed there 2 weeks prior and paid $36 through Priceline name your price.
