Well He died before it was opened so... I doubt he would miss it. And if we are going on the "original Walt view" for
Disneyland the whole Pleasure Island concept doesn't fit. It was not a place to "take your girls on Sunday afteroon as a family" Yes, I know folks took thier kids there, but.... that wasn't the goal LOL!
I have actually done a lot of reading on Walt.
1. The "Saint Walt" view on the DIS does not really appear to jive with reality! As a matter of fact when it came to "merchandise" one of his first deals was to sell Mickey stuff that only HE got paid for and not the company. (Roy was not happy as this presented issues with bankers etc LOL!) Walt also engaged in what we would refer to as "union busting"
2. Walt liked to make money. He liked to spend it too, but he did like to make it.
I often think that with his attention span.... he would have long ago moved on from amusment parks. He moved on from movies (see union busting) to amusement parks.... I think he would have found something else "new" if he had lived longer.
