For what it's worth... I spent a lot of time today research this exact question. The Union Square East area for Hotwire is larger than Priceline's, and includes the Moscone Center area. There is currently a 4 and 1/2 star hotel offered in this area for $139. If they are using Hotels.com, there is only ONE hotel with that star rating: The Intercontinental. Just in case anyone is interested. Want to give back a little here. -- John
