O'hare Valet Parking, Terminal 3 - May 1

Rating - 9.99

I called, they answered (that is kind of a miracle), and my car was waiting when I got there.

Best thing I learned (thanks Pete) is when you pay in valet, you get a ticket to get you out that you can use in the "key card" slot (don't have to wait at the booths) when exiting.
