I visited the Willis Tower just after opening at 9am, and there was already a sizeable queue. There is a dedicated line for City and Fast Pass visitors. The regular admission line had waiting times of 30 minutes, but it didn't take that long. As security is in place, jackets need to be removed and any small items need to be placed in a bag or your jacket. Once at the top of the Tower, the views are incredible. There are extended viewing booths where you can have your picture taken or take your own pictures, but I didn't bother as the queues were too long.

The first time I visited the Skydeck was in 2012. I was impressed with the experience, learning about the tower's history and how fast the elevators were. Once at the top, it was a little disorienting being up so high, but being able to see so far out was incredible. Highly recommend checking it out and taking in the view.

I have done this two times in the past 35 years and I don’t need to return. The plexiglass boxes are an attractive nuisance that gums up the movement on the observation deck.

While you should experience— two times is one too many.

Skydeck provides an excellent view of Chicago in all four directions. On a clear day, you can see 50 miles out to Wisconsin, Indiana, and good ole' Joliet. We were most pleased with the service. We had a stroller and were escorted through an accessible entrance and service elevator to join the ticket line. You should not worry about taking a baby up to the top!
