the location is right near ohare, so there should be plenty of hotels in the area for you to stay at.Nah I'm flying out on the 12th to make sure I'm there. I haven't received a confirmation as to where the exact location is, though. It shouldn't be too bad finding a hotel wherever. I'll be pulling my "airline employee" discount card.
