I loved having this card! I went on 2 cruises, museums and to the John Hancock Observatory. It made me go exploring and that is the beauty of it. Chicago is a lovely city.
This card is well worth the money. I visited 7 events, plus the 2-days hop-on/hop-off with the 2 day card. One thing to keep in mind is the "skip the line" only means bypassing the ticket purchasing line, not the fast pass.
Well worth the money. We enjoyed over 8 sites and got to the front of a couple lines. We'd buy them again in our next trip to Chicago
