While we await more reviews submission - Here's another tip posted on a forum recently :
"Hotel Marriott o'hare. Its just 0.02 miles (2 mins walking distance) frm the center. Its a nice hotel and not too expensive either.They have their own shuttle from airport to hotel every 15-20 mins. If you go through the USMLE.org website - they offer an examinee discount too"
