I agree! A Pinocchio's Daring Journey dark ride would BLOW ME AWAY! Pinocchio is one of my favorite films (not just by Disney, but ANY films!) and I completely agree that both the character and the film are underepresented in the MK. Also, my case for it is that the Pinocchio ride is NOT a Disneyland exclusive - Tokyo and Paris have it, too! So why can't we? It's missing in Hong Kong but there are a LOT of things missing in Hong Kong!
The Alice dark ride/land would BLOW ME AWAY as well! Especially if it was based on the look and feel of the 1951 Walt Disney Animated Classic film, rather than the current Burton one.
I wouldn't have guessed a dark ride for Dumbo, but they do have the Casey Jr. Circus Train attraction at Disneyland which was later adapted for Disneyland Paris. Perhaps this would be the attraction, if the property in question is Dumbo?
I'd be excited for any of these three, or a return of Mr. Toad (which seems unlikely), or a dark ride never done before, such as Beauty and the Beast, Cinderella, Sleeping Beauty, etc.
I can't wait to find out what it/they will be!
