Ok, let's start developing this.
Firstly, personally I like placing the ride behind Haunted Mansion if only because I'd rather it be a part of Liberty Square than Frontierland. I think that it would be really cool to have the queue wrapped around HM right on the water. I think that we'd be able to narrow that section of RoA to add the path/bridge/ whatever.
In terms of the set up, these are my initial thoughts: 1801 in the Ohio River Valley. Guests leave the safety and bustle of Liberty Square and, eventually finding themselves in an abandoned frontier settlement nestled deep in the woods. Coming across an abandoned Keel Boat Company, guests board a boat and set off down the river, traveling deeper into the forest, encountering the Sasquatch, one of the many water-borne cryptids, and others all being pursued by the Wendigo. My initial thoughts are to have this ride be pretty dark in tone. Disney's never done a true horror dark ride so it'd be interesting to explore, though, of course, there's a line we have to carefully walk so we don't get ruined by the realism score. In terms of structure, I'd love to have the ride start outside before transitioning into the dark ride portion, which would be most of the rest of the ride.
In terms of ride system, I think that it might be worth it to look at Shanghai's PoTC ride system. It's super dynamic and it would let us really put guests in the center of the action. It'd be amazing to have guests be actually affected by these cryptids.
In terms of presentation, if we end up going with this, or a similar, direction I want to try to create a soundscape for the attraction. I did something similar years and years ago for Sorcerer's Apprentice where I scored an attraction with a bunch of Aaron Copeland music, and I think that this would be a great way to immerse the judges/ whoever while they read the project.
So, what are we thinking?
