I really enjoyed my time here even though I don't usually like museums and I certainly didn't understand art (especially pop art, whatever that still is).
If you are a local student, you can use your ID for a free bus ride and free admission. Awesome! I think for students from other schools, admission is 1/2 off. I did see a parking lot right in front of the museum if you bring a car.
You start at the 7th floor and work your way down. Since I don't know anything about pop art and minimal about Andy Warhol, I had more fun going through the timeline of his life.It was more interesting for me to go through his life and the events at that time (and how it influenced his art) more than the art works itself.
I also enjoyed the time capsule room they had- there was one capsule (out of 60 or so) that was opened and organized, and it was really cool to see the people that sent him letters, invitations to social events, and even old memorabilia. Really cool.
Also take some time to walk over the yellow Andy Warhol Bridge (7th Street Bridge) and enjoy the views of the river and bridges and the downtown buildings on the other side.
