I've stayed at the Hyatt many times, even though I've never been there for a group or convention. It's conveniently located, being a $6.00 cab ride to anywhere in the Loop/Magnificent Mile/River North area. The rooms have always been clean and fully stocked. One time I got an upgrade to the parlor of a suite - it had a Murphy bed, but it was as big as two regular rooms put together. Views north of the river and Streeterville are much nicer than the views south, which are blocked by the BP building. Only negative - a big convention can fill the place up and make you feel out of place and awkward.
Pros: Convenient location, clean rooms, Hyatt standards
Cons: Convention crowds
