We are staying at the Hyatt Regency for a conference DH is attending at the Fronteir center in August. I will have Monday through Friday to entertain myself but no car to get around. I've identified a couple of things within easy walking distance of the hotel but was hoping someone(s) could offer suggestions for what to see or do for a first-time visitor. DH will have some time a few of the afternoons and hopefully all day Friday, so I want to plan some things to maximize his free time as well. We like to do "overview" tours of cities and I see there is a boat tour offered, and I do want to go to the Milwaukee Public Museum. But what else?
