I had purchased two day cards, went to redeem the voucher and was given only a one day card. The second day I went to the museum and was told that my card wasn't valid. I had to pay out of my pocket to go in because I didn't have time to go across town to get this straightened out. I had requested a refund and three weeks later I am still waiting for my money back. The town was great, but the experience with this card was horrible. I will never use it again in any other city it is offered in.
I would not do this again. Granted you are not responsible for the weather (rain), but just trying to figure out how to use the card was frustrating. No one was very helpful. In short, it was a waste of money and a big disappointment.
We had 3 days to spend in Chicago, and wasted a lot of the morning of the second day picking up the card and information booklet. There should be advice that the card can be picked up at any time, and the two days limit does not start till the first use. That would have been very beneficial to us. We enjoyed the river cruise, and visit to Robie house, and John Hancock Tower, but could have done a lot more if we had picked the card up earlier.
