We took our kids to the children's museum on a hot summer day. The place had a lot of hands on and the kids had a blast but it was hectic and a bit dirty. I felt like things are not repaired quickly and there were several things that needed attention. I've gone to many of these and this one is up there with the best of them. I wouldn't drive to Milwaukee just to go, but if you are in the area it is worth a side trip. My oldest is 6 and it might entertain her for a few years more.
