I love scary stuff and my wife is terrified of it so I'd say a solid 7, but if you go with someone who scares easy it's an easy 9.
It's a hard question to answer. It's mostly the jump-out-at-you kind of scares. The atmosphere is very immersive, but i wasn't scared of my surroundings. I'm not very easily scared, and i wasn't here either, but even so i enjoyed myself. My wife was screaming through the whole thing and she also enjoyed herself. I'd say the actors are a 7/10 scary and the atmosphere is 6/10, but overall 8/10 (not an average)
If you get scared easily they have low fright during the day where there is no actors but animatronics still on. During night I would say 7. Actors jump out.
