Its self guided through 2 buildings. You can schedule a private tour with Don Garlits. Call to schedule.
When I went on Saturday we just walked through it by ourselves. Two buildings. However, agreed call them between 9-5 they will be able to assist you better.
I can't answer sorry but guided or not it's a huge exhibit that you will love. Enjoy.
You can call them and ask about a guided tour. Go to their website and call during business hours.
