Yes, I saw buses there as well.
They do have overflow parking, but that may be a question best directed to the park itself rather than Google reviews. I don't see why not though. Pretty sure there were at least two there when I was there a few weeks ago. Also, they do have busses that come up there.
There is a big dirt overflow park on the opposite side of the park. With an underpass to get across the highway.
For sure there's plenty of parking!
Across the street. Then use the tunnel to make it there safely.
Saw one there
