Nothing special
We stayed at the Hyatt for a conference I was attending for work. Party included my wife, myself and our two boys (6 and 2).
Location was fine, view of river/navy pier was nice, as was check in but had requested a room with two beds, which an accessible room was the only available I guess. No biggie we thought. 
However upon getting into the room, there was a total of about a half square foot of available counter space in the bathroom, and the door to the bathroom consisted of a sliding door (which was less than ideal with having the kids from a safety/privacy standpoint). What we couldn't figure out was if it was an accessible room, why did it have a step in tub in the bathroom?
Long story short they seemed to try to satisfy the accessible room minimums (very poorly in my opinion) but also made the room less than functional for other guests as well. 
For $250 a night and being a Hyatt I expected more.
Have stayed here in the past as well and come away less then impressed, won't be back.
Would look elsewhere for a room.
