The bodies exhibit is extremely educational. The disections are superb and well worth the trip if you are a bio, health sciences, or premed student. My wife and I went with the University and got a discounted rate since it was such a large group. We were lucky enough to have our anatomy professor come along and explain everything to us as we went along.
The exhibit does also have small "telephone receiver" devices that explain the exhibits as you go along. I think it is well worth the money.
