If you’re visiting the Magic Kingdom on a day when Mickey’s Not-So-Scary Halloween Party will take place, the park will close early that day. Right now, it closes at 6:00, even though the party doesn’t start until 7:00. That gives the Cast Members time to clear the park of guests who don’t have Not-So-Scary tickets. Typically, the Magic Kingdom is less crowded on party days, so I’m not saying to stay away. It’s a great time to use Park Hopper if you have it!
