I've never used either one, but DH has. He said that he'll open up both and he'll see what the Hotwire price is and then he'll go into Priceline and try to beat it. And if they don't accept it, he'll go with the Hotwire price. The only problem is you don't know the hotel or exact location...it gives you a general area. Congrats to your husband on his time! I know you must be very proud of him. ~Lisa
