Well, you could move Norway.
PA has a bunch of amusement parks, great ones. I know Hershey has a lovely Christmas display but I never went even though it is close and inexpensive because it's just too stinking cold. This is why it only works in Florida. I imagine Florida was chosen specifically because it is mostly warm, mostly flat & drivable to the people in the North East & South with the money to sustain the magnitude of WDW plus there are beaches for when people want to mix it up, nevermind the proximity to the cruise worthy ports. It wouldn't work anywhere else.
California fits the same bill for the West. Neither of the locations were picked on accident. It's all location, location, location, businesses live and die on their location.
