Worth EVERY PENNY and then some!
Bought the full tour the day we drove up to Haleakala. Everyone in the car agreed it was worth more than $10 just for that part, and we had the road to Hana and the rest of the island as bonus material! Can trigger individual points manually, so we could replay what he said if someone didnt catch it all - which also helped when we got back to the mainland and could play some for people at home.
