Occasionally you may notice that one of the theme parks is closing much earlier than normal. There are a couple of reasons why this might happen. It could be that the park has been rented out for a private event. Large businesses will sometimes like to treat their employees! It could also be because there is a Disney sponsored event taking place. If you plan to be at a park on one of those days, check to see when or if the nighttime shows will take place.
August 14, 2021 is the perfect example. The Magic Kingdom is closing at 6:00 because a private company is renting it out. Happily Ever After will not be held for the public.
