If there is one attraction that should be a "must see" on any Disney fan's list, it is 'Walt Disney: One Man's Dream' at Disney's Hollywood Studios.
Originally created to commemorate the 100th anniversary of Walt's birth, it opened on October 1, 2001 as part of Walt Disney World's 100 years of Magic Celebration. A few years ago the attraction's marquee was updated to reflect that D23: The Official Disney Fan Club was now presenting the attraction.
