This is not exactly true. Go to My Disney Experience, and click on My Itinerary. Under today's date, on the left side, click Add Plans, and then in the drop down, add parks and places. You will now be looking at park hours, on the official Disney World website. Click on the calendar next to today's date, and you can choose, and see park hours, for dates up to, and including, August 26. Using that official Disney information, I see a 6 PM closing on Friday August 17, Tuesday August 21 (which also has a special ticketed event from 7:45 - 9:00 am EMM), and Friday August 24.
