I don't know anything about the backstage/money/thought process. But if I were to guess, I don't see them changing the ride around. I see them using the track they already have and just redecorating. People are asking about how they can fit Frozen into a 2 minute ride. To me, since not much in the movie happened anyway, they can do it, no problem. They did it with Mermaid, cutting half her story, and Peter Pan. Peter Pan I wish were longer, but they get the essence and theme of the story well for as short as it it. Frozen (if it absolutely has to be done) can do the same.
My ideas:
1. The THEME of the ride is going to be the guests being invited to Elsa's coronation. So the loading dock can either be us already at the docks of Arendell taking a ride to the city...or maybe another Norwegian village on our way to the castle.
2. The track going up (with the Odin head) can be the trolls telling us of the profecy...if not retheaming this, they can keep the dark and use laser style moving troll heads or something like that. Weren't they neon colored and stuff? Anyway, they can yap on about and act of true love or whatever else.
3. then, we find our way into Arendelle already frozen and Elsa has run away. We have AAs of Anna runing off to find her...meeting Kristoff and Olaf.
4. The first troll drop would be replaces...perhaps with wolves and we are chased down the mountain cliff.
5. This would lead us to Anna and Elsa's big moment where Anna is hit with ice in the heart and Elsa unleashes her big ice beast. The ice beast would chase us down the second drop. I see them closing off the boat window so that the whole place is dark. That window wouldn't fit with the story.
6. This drops us down to Elsa going 'oh what have I done?!' and the finale of the movie.
7. The town where we unload at will be re-themed to look like Arendel and everyone is all happy.
Anyway, that's my idea of how to rework the ride. I probably would be too serious and they would need to rework it so that all the 'awesome songs'
can fit into it. But that is at least an idea of how they can get the story to fit the track they already have. If they need a little more for the end, maybe they can get ride of the end dock and keep us going till we get back to the entrance. then the town room can become the 'everything is back to normal'/coronation scene. i dunno.
The old video room would then become the meet and greet.
so there's my input. And I still hate it
