After having an obvious error on an airline hotel voucher this hotel would not allow us to book a room at any price. They suggested we go back to Ohare airport to get correct voucher but all desks were closed due to time of night. After numerous efforts to get a room they refused at any price. We ended up sleeping on the hard chairs at the airport. And this was after 30 hours of travelling with no sleep. I have been a Hyatt World member for years but because of the rude and callous treatment at this hotel I refuse to ever book at Hyatt again. Which is a shame.
