Purchased the Explorer Pass online prior to mid-July trip to Chicago. We rate this as average because it is convenient to obtain and perhaps can save you money based on your personal choices. However, it is not for everyone and its use is somewhat misleading. Examples: If you want to do the fireworks cruise on the Tall Ship Windy, it's not included with the Pass, and there are others like that. For the more popular venues, such as Skydeck, you have to reserve a time and that attraction will only allow a reservation in advance and in person. Some others are the same way, such as the Big Bus Architectural Night Tour, which only departs from the Navy Pier area and requires an in person reservation. We attempted to go on a weeknight on that Tour only to be turned away because the tour was fully booked and we had not reserved in person and in advance. While as a couple we saved a few dollars we found using the pass was not as convenient as we had hoped, particularly due to the "in person advance reservation" requirements of a number of the more popular attractions. If you have to do that, you may as well pay when reserving for only a modest saving otherwise.
