O-M was very good, but their dispatch was a little disconnected . . . they could not find my reservation using my name, but had to have the confirmation number when I called from ORD. The cars were very clean, I would have appreciated a cold bottle of water, when I got in, like I get in Boston . . .
Both drivers were polite, and the car I took back to the airport had a power inverter so I could charge my computer without using the DC power cord.
Price was $63, plus fees of 5.50 and a $10 tip . . . I was happy with the service but this was pretty pricy. I think I will try chimoe's suggestion the next time.
Thanks everyone, I appreciate the help!
