All of you are correct. Yes, every executive needs to experience and understand Walt's legacy. And so does the Disney consumer. Walt Disney Productions used to understand that. It goes so far to inspire and instill loyalty. People with good business sense would actually understand that; but I am afraid the newer management gets so caught up in the here and now that they just forget that. And it is not just a generic sense of history. It is truly a story that inspires.
Walt Disney World has enough land, and even the name, that Walt Disney's story need not ever be cast aside there. It should always be told there.
The best place for it, though, is NOT One Man's Dream nor in the "studios" theme park. It is in its original location, the site built for it: The Walt Disney Story attraction, artifacts and final film just like the OMD attraction, should be restored to the Opera House (I think that is the name) on the East side of Town Square, where it was originally housed. It belongs on Main Street, USA, as "The Walt Disney Story" attraction. It inspired me when I was young, and set the stage for my understanding of Walt's dreams and of Walt Disney World... and is clearly the genesis of a lifetime fan. Had I not had the 15-minute attraction, I know that I would not have understood WDW, EPCOT, and Walt's dreams, and been such a deeply-rooted fan today.
Disney still honors its past all the time in many ways, such as nods to older characters in current films, or in attractions throughout the parks. Even One Man's Dream in WDW (though built for the 100 Years of Magic promotion) is a reference to a similar attraction house at Disneyland for many years under the same name. (Look it up. You will find it in "Disney A-Z," an excyclopedia of Disney facts that itself is enough to make you weep about some things that the company used to do when it believed in itself as a leader and innovator, not just a company of "branding" and "intellectual property." -- That book is a gold mine for a real Disney fan.)
So, while it still has people in the company who love and reference the past, I think that The Walt Disney Story (or "One Man's Dream") should always be told at Walt Disney World. And I think that Main Street, USA, in the Magic Kingdom is the place for it, not necessarily a warehouse studio building on a "studio" backstreet. Lillian Disney even cristened that attraction when they opened it in honor of her late husband in the park and resort built to honor her husband's legacy and to carry his name.
Close the DHS attraction and bring "The Walt Disney Story" back to Main Street, USA, where it belongs. And while you are at it, go ahead and restore a "One Man's Dream" attraction with similar features at Disneyland. Keep telling the story.
