Wow - I wish I had found this site a long time ago! I just returned from 2 nights at the Chicago Hyatt Regency Loop (2/11 and 2/12). I got the $70 PRICELINE rate on my first bid. I have been using priceline for a few years, and have gotten the Hyatt Regency twice before, both times at about the same rate. I have always been happy with it, but this was the best. We got into town late on Wednesday. Service was great - in fact we were upgraded to the Regency Club room, for no extra cost. Room on the 35th floor, we needed to use our key to get floor access. The view was stunning and room was high quality. We didn't have much opportunity to enjoy the perks of the "club" but everything was quiet, high end, and great service all around.
