The OP may find more objectivity when reading one of the many Chicago travel guidebooks or by visiting the Metromix, Time Out Chicago or Chicago Reader websites. That's what I suggest. About Navy Pier ... it's a huge attraction, not just to tourists ... and if you spent a couple days there you probably couldn't fit-in all there is to do. The panoramic views of Chicago's lakefront from the pier are spectacular. But do some more independent investigation to find things that interest YOU and not the rest of us and check back to ask some specific questions. mid-September is usually an excellent time of year to be in the city. Thanks.
