My daughter and I took the Architectural River Tour departing from Michigan Ave. The tour was informative and the views enjoyable. We made the mistake of sitting at the back row of the top, where the guide's commentary was hard to hear. As a result, I think we were slightly less engaged with the material. If you take this tour sit where you can hear. It was also hot, hot, hot, in the sun, so be ready to sweat.
Advice to Shoreline: make sure your PA systems cover the boat.
