It may not be a simple 1:1 here, however I’ve thought about this land a bit yesterday, and this is essentially going to be our Fantasy Springs. The main ride should absolutely be the Peter Pan ride system. It’s going to be a complicated E ticket with MANY characters, this ride system feels the best way to handle that, and would be unique to Magic Kingdom. Take the Tangled Boat Ride and make it either Ursula, Hook, or Scar themed. Instead of the Frozen boat ride, give us a massive roller coaster. Maybe not quite in terms of height/drop wise, make it Expedition Everest in scale and story wise. I think they absolutely have potential here with that being their base ideas.
Some random rambling, but it’s helping me envision this land a lot better.
