Did it last Saturday and it was soooo cool!
No behind the scene stuff. He had us sign a waiver and wear bright yellow vest. Just saw CM's getting park ready. Could bring phone but no photos allowed. Appropriate shoes...no sandals, etc.
I'm a very fast walker and we kept that pace. 5 of us did it. 30 minutes and we made the loop from Grizzly to paradise pier to back entrance Carsland, through bugs land, past Guardians, down Hollywood, and back to entrance.
He was open to questions. Would love to do again in the future.
