Hi! DH and I are taking DD (almost 2) on a few night trip to Wisconsin. We have a hotel in Madison but can pass through Milwaukee on our way. We're going to end up in the Dells as our last stop. We're looking for a few things to do in Madison, Milwaukee or the areas between there. We were hoping for an aquarium, but I can't seem to find one! I saw Madison has a children's museum, so we'll probably check that out. We will be traveling in January, so outdoor activities are probably out. Any other suggestions? TIA!
