I'm giving this hotel a low rating due to the inaccurate information regarding the schedule and arrangements for their airport shuttle. If you call the hotel phone number there is an option for "shuttle information" where there is a recording indicating that the shuttle runs 24 hrs per day, at 15 and 45 on the hour with pickup at the Shuttle Terminal Gate 1 at Chicago O'Hare. Moreover, I received a text message reminder of my stay with that same information. Accordingly, I went to the Indicated pick-up spot on arrival (10:30pm). No shuttle came at 10:45pm; ditto at 11:15pm. At 11:30pm, I decided to call the hotel. Not easy to find the phone number, as Googling gets you the main Hyatt reservations number. When I finally got through to the front desk they informed me that after 10:00pm the shuttle only comes when you call to request it. So basically I ended up waiting more than an hour for the ride from the airport to the hotel.
