We bought the Go Chicago Card and were given access to one day on the Big Bus Chicago Hop on Hop Off Tour. Our hotel was located near both stops 1 and 13 and we decided to start at stop 1 for our day. It was a little difficult trying to figure out where the stop was, but once we figured it out, it was very easy to have our card scanned and given our bus tickets for the day. We had also downloaded the app to get access to the current bus situation. We used the hop on hop off tour to see Chicago and get us to the other attractions. We hopped off at stop 6 for the Adler Planetarium and hopped back on at stop 7, the Field museum. Because it was still the off season, we waited about 30 minutes for the bus. We took the bus from stop 7 all the way through the other stops and hopped off again at stop 3, the Sky Deck. By this time, it was the end of the bus' day, so we knew we would have to figured out a way back to our hotel when we were done, but we didn't mind. My husband and I both thought the bus was the highlight of what we did. We were able to see a lot of the city and get some history and able to get to the places we wanted to go. Would definitely use the Big Bus again!
