Something that Thorpe haven't attempted at yet (well, The Curse was the closest we got) is an actual ghost themed maze.
I don't mean family - I mean they could have a maze themed around a haunting and make it very scary. Instead of jump scares it would rely more on a scary soundtrack, tension, well themed sets and things like that (with the odd jump scare thrown in as well to keep tension high).
A shame that they didn't pick a film that could accomplish this, but I'm still excited for what we've got
