^ I remember the special made around DL's 40th, that had the actor who played Harry in "Night Court"? Hosting the show about DL's history, present and....the Future?
In that special, they went thru the upcoming attraction based on The Little Mermaid - you guessed it - the old suspended clamshell ride, since 'shellved,' heh heh.
I think the whole concept of the DL Tomorrowland Update was in it too, including a first-look at "Alien Encounter". For Disneyland.
Hmmm. Well, plans DO change - even in TV Land.
(EDIT: Had to add more, more.)
