Pros: Work outside, free apples once in a while, free admission to the park, preview of all the haunted attractions the night before opening
Cons: Bad management, disrespectful atmosphere, negativity all the time
None of the management knew how to communicate with each other - it was a giant game of "pass the buck" the entire time. I worked in the Halloween Haunt department, and although the title of my job was "creative team member", there was nothing creative about it. The bosses would listen to your suggestions, immediately reject them because of some small problem that would be very simple to solve, then weeks later put the idea into action under the guise of it being their original thought.
The hours were fine, but the pay was far too low and no one ever got a raise. I have a few friends who worked there for over four years without seeing a pay increase. We got no benefits, and there was either absolutely no work to keep us busy or way too much because management didn't know how to properly delegate or schedule anything.
Bottom line, don't work there. It's awful.
