How awful would it be to have two 12 year olds there alone?

I wouldn't leave my kids alone

Well i wouldnt leave any 12 year old alone in any haunted house, however this was not that terrifying. I just returned from darkside acres, way better of a scare.

I think you should have someone at least who is brave enough and isnt scared go so that if the 2 twelve year olds go and get scared it wont be a waste of money

Depending on the children it should not be a problem . if they get to scared there is security on the grounds at all times that would help them

Not that bad scare wise if they are good with jump type scares.
