I saw someone else write this and suggest it was "a rumour" he had heard somewhere.
I do not profess to any rumour... this is just plain fantasy conversation and opinion....
So lets discuss the idea of the Matterhorn becoming a Frozen themed ride.
I know the traditionalists, to which I consider myself to be, would think the idea terrible but I want you to consider a few things...
Pirates had both the political correct update and then the Jack Sparrow-a-thon. I am sure some hated it and may still do. I myself miss the old soundtrack (He Knows Too Much!) but have become very happy with the update.
Finding Nemo is perhaps the best example of re-Imagineering a ride into a modern adventure.
Swiss Family Robinson becomes Tarzan.
Even classics like It's a Small World took on a "Where's Waldo" theme when they went away (not far away but away) from the original concept of children of the world sharing a thought of peace and connection to the addition of Disney Characters.
So why would a Frozen Ride not be acceptable at the Matterhorn? After all, in the beginning it was a wooden structure with skyways going through it so the Snowmen are not original either.
I really think this idea has merit!
It won't happen until after the 60th Party as there is not enough time to put together some scenes and figures.
Imagine.... there could even be an abominable snowman hiding in a Skyway Vehicle somewhere as a tribute to the past ala the three heads in Winnie The Pooh.
