I've been staying at the Crowne Plaza for the past couple years now EVERY time I fly out of O'Hare!! I live in Michigan and it's about a 2 hour drive for us to catch a plane. GONE are the days of us leaving Michigan at 3am so drive to O'Hare to catch an early flight. (not to mention trying to find someone to take us there so we don't have to pay for parking!!) My husband and I travel about once a month and have made the Crowne Plaza our second home!! I've stayed at the Hyatt by O'Hare and although the Hotel is really NICE, I heard jets flying by all night long. I was shocked since the 2 hotels are so close together. I LOVE being able to climb into a clean fresh comfortable bed, get a good night sleep and then be taken right to my gate in the morning. Their shuttle service leaves the hotel on the hour and half hour, and leaves the airport on the quarter and three-quarter hour. They are so prompt, when we get off the plane and grab our luggage, we know exactly how fast we need to get to the shuttle area in order to catch the next one!! (if you fly International, you just call the desk to let them know you've arrived and the next shuttle will swing by and pick you up) We've never had a bad room or a bad experience over the past few years!!!
