DO NOT USE THEM! - HORRIBLE
One I used express and the hotel was not a known name, not in the area that was shown, its not downtown Seattle where I wanted not near anything. Somehow it also got nilled to my daughter (she uses the computer too) Not sure if its hackable from there program or what. But they will not fix that either its NON CANCELLABLE and they are NON CUSTOMER SERVICE! HORRIBLE! And the price was not cheaper one they add everything on I could have gotten the Hilton for over 100 dollars cheaper - DO NOT USE THEM!
