Great find!
Kinda interesting how the front entrance and about 80% of the park are basically exactly the same. If you were to film the very front entrance and a lot of the park for some found footage movie set in the late 90's, you could easily sell it with some VHS visuals.
Now if only we can find some footage of HHN Hollywood 1999. I've looked everywhere I could for any footage I can find, but that event has been completely memory-holed by the internet.
