Well, I think a Raft Ride with seats facing outward would be unique, although I don't quite see the purpose for a raft ride for ENG, how were you relating this to the movie, the part where they go over the fall?
I think just a normal dark ride could do the trick if anything, most people would be against putting in any such ride about ENG simply because of it's dismal popularity, which there are valid points on both sides of the argument, but that's another post for another day.
