Chicago O'Hare...do you know any cheap & good parking around the airport, with shuttle available to an fro?

My parents are going on a trip, a short 4 days long.

They want to drive to a good & as cheap as possible parking place. They are traveling light, so from the parking they want to be shuttled over.

The O'Hare parking is ridiculously priced, so do you know of anythign outside of the O'Hare system?

My suggestion, don't take the car. Take public transportation. They can take the CTA blue line. Or they can take the metra. The blue line takes you directly to the airport.

The metra has a shuttlebus and a Tram that takes you to the airport. http://metrarail.com/Sched/ncs/ncs.shtml

The only problem is that the Metra train to Ohare doesnt run on weekends.

take the blue line, goes straight to the airport, $2.
