The show includes over 500 photographs taken that day by in park PhotoPass photographers and over 5,000 photos in all. It is presented just prior to the Wishes fireworks show.
The new addition is part of the "Let The Memories Begin" celebration theme at the Disney Parks for 2011.
In order to help explain what the show will look like, here is a short video clip from DisneyParks and the Disney Parks Blog. Enjoy!
