I think the answer stems back when Walt Disney was alive.
Back when his daughters were young, he grumbled that the places where
they could go as a family were usually seedy carnivals and such. Or
amusement parks where he would sit on the sidelines while the kids went
on the merry-go-round.
Then when he took his family to Europe, he stumbled upon inspiration in
the well-maintained Tivoli Gardens.
Disneyland was probably born on the European trip. Walt wanted a place
that both appealed to kids AND that adults could enjoy, too. That was
the cornerstone of his vision of Disneyland. It was built to be the place
where kids "of every age" (meaning adults, too) could enjoy themselves
together.
So I think VMK is an extension of a Disney park. Adults who love to go
to Disney parks enjoy playing VMK. I can't speak for all adults who
love Disney, but this adult sure does.
