I think something like this might work for Carowinds. From what I could find this land is all owned by the park, it puts the station in a pretty good spot behind where Drop Tower was, and the terrain would work pretty well for the first half since it's going uphill there. The main issues that I could tell would be dealing with the terrain in the second half and rerouting that perimeter road, and I don't think either of those would be too too difficult to get around.

RIP those poor souls who are staying in the dorms right next to it.
