Honestly, keep trying. I'm surprised that they haven't answered, but they stay busy. I'm also surprised they haven't expanded the park because of the demand.
You have to call. There is no on-line booking. Good luck!
They were jamb packed the day I took my tour.
I'm sorry to hear that but don't give up the place is worth it! They may be away from the desk..
