Disney World parks in Florida began reopening on July 11th after being closed for four months due to COVID-19. Now all four theme parks are reducing park hours beginning September 8th.
The hours at Disney's Hollywood Studios, Animal Kingdom, and Magic Kingdom will all close an hour early, and Epcot will close two hours early.
The change isn't drastic, and it certainly won't prevent the spread of COVID-19, but it indicates that it could be related to Disney's new safety measures, which include mandatory face masks, limits on the number of people allowed into the parks at one time, as well as increasing the cleaning schedules.
Disneyland in California remains closed.
