Here's what you need to consider Scoob...
You won't be at Haunted Castle a lot, you'll be there sometimes, but not every single day, your other rides will be Pixie and Dixies Swings, Jetson Jet Orbitors, Boulder BumperCars and the thing they call squid. So, you need to think if you'd mind spending a 16 hour shift at one of those rides as well (which you wouldn't unless it was an emergency.)
Anyways, I'd try to work in the park, it can be hard or easy to fit in, Alien Seed (good ol Jeff Kohorst) had trouble fitting in he says, I had none at all. It just dependson how outgoing you are. Good luck either way, and don't be annoying about anything either, cus that gets you no where.
