Chris is a great tour guide. If you want someone to chauffeur you so you don’t have to drive thru the park, and just sit back and observe then that would be something for you. Else you can drive yourself there and sight see. I thought it was too expensive for just that, and on top of it you have to pay for the entrance to the park. That was a surprise to me. The tour guide keeps your CC receipt for the entrance pay you made. Sorry, but I find this very weird.
