Okay, you Chicagoans and veteran visitors. Tell this first time visitor how to make the most of his 48 hours in Chicago from October 19-21. I'm interested in evaluating the famous deep dish pizza, and want to see to various neighborhoods, rich and poor, key must-see spots/landmarks, and perhaps a drive through the John Hughes suburbs I've seen so often in movies. Wish I could go to a Cubs game, but I guess not. Have zero interest in galleries, museums, and that kind of crap. Also, of these four hotels, is there one or two that is much more interesting or better located than the others? The Wit, The James, The Seneca or The Hard Rock.
