Here is the situation: Family of 6 staying at Disney from 28 Aug to 5 Sept. Oldest HS age daughter is big HP fan, and is reason we are including WWoHP in the itinerary. The rest are a set of 6yr old twins, and a 5 yr old daughter. I had planned on getting them up at crack of dawn to high tail it to WWoHP first thing one morning. Now, I am starting to see recommendations of EVENING visits.
as pp pointed out, the park will start closing earlier. Aug 28 is the last day on the schedule for it to be open until 9 pm. After that it closes at 7, and then 8 pm on Sep 4 and 5.
