I'm trying to attend a gamesday (usually its LA, but due to circumstances, I was unable to make the trip out this year) So I thought I'd try to head out to the one in Chicago.

Problem is, I've never been out there, and I am not familiar with the geography, nor where the gameday is being held. If any other gamers who have been/planning on going, could you please inform me as to where I should look to concerning local hotels and which airport i should go through? Any information would be greatly appreciated.
