I just bid and won Hyatt Embarcadero for $81/night for 6/27/10-6/29/10 based on info from another thread. I used the link to PRICELINE from here. Thanks so much!
I just booked this for 5/28 for $133. It is indeed The New York Helmsley Hotel, listed as 3.5 stars, restaurant, business center and high-speed internet. I used the link to HOTWIRE at the top. Thanks for such a great site!
