Greetings! We’ve decided to add some activities; MSID, Uof Chicago, Hyde Park; Field Museum and Shedd Aquarium. We are intrigued by the train as a mode of transportation. We are staying in the north Michigan area. I’m already confused with CtA & Metra and bus. What would be the best mode(s) or combinations of the listed to use? We’ll be in the city for four days so any recommended train/ bus pass would be helpful. Thanks.
