We did this walk with a tour guide, Jan, who was very knowledgeable about Chicago architecture and history. The boat ride looked like fun too but we wanted to see places on foot and I am so glad we did! We were able to stop in and see lobbies of historic bldgs. The Art Deco Chicago Motor Club Bldg (now a Hampton Inn) was a definite highlight. It was just the right amount of walking, no stairs to climb, maybe not the best for young children, but for those interested in urban history, it was great.
