Brother has a flight out of O'Hare in mid May at 6 AM. Any parking recommendations that are fairly easy to navigate. Weather shouldn't be bad so wouldn't need to be covered. A see a lot of shuttle services from hotels and such don't begin til 5AM. He is 3 hours away so wasn't planning on getting hotel. Just arrive, park, and fly out. Any idea of pricing. Car will be parked for 8 days. Thanks
