They never sent us the passes because they made a mistake with our e-mail address initially. We were at the planetarium waiting for one and half hours for customer service to get it straightened out. In the time that passed, they sold out of the show that my son wanted to see. The planetarium felt sorry for us and allowed us to enter for free. When we went to take the big bus tour, we hopped on only to find out that we had to have processed our passes prior to getting on the bus since they had no way to process our passes. We had more wasted time.
We had a great time, hopping on and off at different museums and events. Each tour guide was unique and interesting. Thanks so much!
Explorer Pass is the best option to visit Chicago. So Flexible and easy to use.
