I was going to suggest the Van Galder bus into O'Hare from the Elgin Ramada for $10 each way with free parking at the Ramada, but after checking their website again it looks like they don't stop in Elgin anymore. I have used this service a couple of times in the past, but if they no longer stop in Elgin it isn't of any use anymore.
