Very useful for admissions to sites. One address for picking up card was out of date
This card can be good value, especially in the summer time when the cruises are open (worth noting they close during the winter). One tip would be to get the 3 day card (or the lowest one available if it's not the 3 day one).
We spent 2 days in Chicago. We stayed in the suburbs so by the time we picked up our Go Chicago card we were a bit stressed about getting our money's worth. Everything has to be done by 5:30pm so you are on a time crunch if you start late. It was confusing at first because we thought the card was our ticket but it was not. You still have to get a ticket for everything you do. Getting the bus tour and trolley requires a ticket from the Palmer House Hotel. The trolley and bus tour guides were helpful and knowledgeable but there wasn't really a schedule so we spent a lot of time waiting for the trolley. The visit to the Willis tower and Aquarium made it all worth it as we bypassed the line ups! Definitely worth it once you figure out the system!
