I believe there are accommodations for that. There are several different parking areas located in the area. It's a very large area and there are several other venues. I believe it used to be a military base.
I remember seeing a school bus there.. I think the parked across the park/grass to enter the museum. I would call the museum and see what they recommend but i do remember seeing at least 1 bus as there was a field trip going on
There's drop off locations. I didn't see mini bus parking but i imagine you can buy two parking spots. It's recommend you go by public transport. At all times since parking is limited.
There is a large car park in front but you will have to check directly if it can accommodate your vehicle
