I must recommend ChicagoTARDIS on principle; it has enough going on to keep you moving, but it's not overwhelmingly huge. And if they stay in the same hotel next year, there's that nifty mall across the street, and some very nice restaurants. (I'm seriously considering just going back to the location when money's not so tight to enjoy the surrounding area!)
