I will only take the tour again if they change everything other then the rides ...
I was not interested in the stories (this coming from history teacher though) ... they need to add more surprise and that doesn't really mean scary ... but things like the pumpkin appearing in an area magically when it wasn't there before, etc.,
I think the tour is too hyped up for what you get ... But I think everyone should do it once ... My city's local Ghost and Gravestone Tour was 30 bucks and we got a snack, drink, flashlight and better stories.
I did have highlights from the Disney tour: rode the ToT with all the bellhops (we asked them to join us b/c they were all waiting to take the last ride after us) and things like the magically appearing pumpkin and odd scream (I think we were supposed to see a light fliker but it never did, I think we were late b/c Gracey kept looking at his watch then the window a couple of times)
