Travelocity Verified Review
"Very convenient overnighting at the airport. We arrived late in the evening and had an early flight the next morning.
Be careful, there is also a Hyatt Regency at the airport, but it is not easy to walk there from the terminal if you have luggage. You have to walk through a parking garage and up and down several flights of stairs. We were directed there in error by airport staff at the baggage claim area. I just asked where the Hyatt was. Make sure you are getting directions to the Grand Hyatt and not the Hyatt Regency"
