Great first post. I’m glad you kept researching and didn’t fall into the camp of “it just must be a new, fun location that has no bearing in HP cannon”. It instantly makes me feel better about the integrity of what is likely to be the best coaster in Orlando.
So clearly, JKR/WB/UC must have thought a made-up setting was sloppy as well. Who would’ve thought?
Like I said earlier, I’m hopeful we see this location in Forbidden Beasts (just the location, of course). That would tie it in even more.
