My husband and I are planning a 4 day trip via train to visit Milwaukee for the first time in April and are looking for some advise on where to stay and what to do? We are in our early 30's. We are hoping not to spend too much money on transportation. We like to walk around to see new things, eat, drink, shop...and are open to any other suggestions! What's the best way to get from the amtrak station to downtown? Best centrally located hotel that's reasonably priced? And what are some of the must do's? Thanks so much!
