There is a tour and a film for one price, and a tour only for a lesser price..... I'm a senior and I had a 10 yr old child with me.... The tour only was beyond enough info for the child, she absorbed quite a bit of info.....I can't remember what I paid for both of us, but it was under $20..
The tour admission is $10 dollars per adult, $8 for seniors & college students (18+ w/ student ID], $5 dollars for children ages 6-17.
If you take a tour, which I would suggest, it was free. I'm sorry, I don't remember seeing what it was.
