We did get a killer deal thru PriceLine ($90.00 per night) and stayed on the 5th floor in the West Tower. The view was great - looking out onto the Chicago River with a glimpse of Navy Pier. The room was loud; we heard everything going on in the hallway and in our upstairs neighbors' room including when they went to the bathroom. If you can avoid parking at the Hyatt Regency Chicago, you should - the cost is $50 per day.
Cons: you are charged for everything - parking, wi-fi, bell service, etc.
