Booked this one through priceline for the last night of a recent trip for $95 (a jaunt to Indiana to see family book-ended by good times in Chicago). We weren't expecting much, just a convenient location and free shuttle to the airport for our very early a.m. flight. Boy, were we pleasantly surprised! The hotel was beautiful, the staff was great, and the room was fantastic with a very comfortable bed. We could also see downtown Chicago from our room...which promptly inspired us to use the free hotel airport shuttle. We caught a free ride over to Midway, hopped on the orange line into the city (took about a half hour or so), geeked out on the Sears Tower, had a nice cocktail and some appetizers in a very nice downtown hotel lobby (sorry, don't remember which one), and caught the last train back to Midway--where we were promptly picked up again by the free hotel shuttle. Awesome. We couldn't have spent a better last night in Chicago and were totally not expecting to sneak in one last hurrah out on the town! In the morning we got a drama free shuttle back to Midway.
I don't know that I would recommend booking a Midway area hotel for a fun trip to Chicago...we actually got our room downtown (Hyatt Regency) for the first two nights we were there cheaper than the Marriott...and riding the train back and forth would probably get old after a day or two...but I can definitely recommend this hotel.
