Hello. Based on some of the recommendations here, I decided to try out Priceline in addition to Hotwire. I started out looking for 4-stars in Lincoln Park and North Michigan Ave for $75. Then I added the Millenium Park area, and upped the price to $80. Then, finally, I added Greater Chicago, and dropped the price to $70, which was accepted by the Hyatt. I'm not sure how crazy I am about the location--but the price is right, and I'm sure the kids will love the pool and being close to the Field Museum. Thanks for your help--of course, I used the link from BetterBidding.com. Jason
