I’m down here now. We did EA today at IOA. After HP FJ and getting Butterbeer, we left the area to get closer to Kong. There was an employee letting people know that Kong wasn’t open but we were free to queue.
I don’t know what time they were letting people leave HP to get to Kong, but I did not notice a rope off between Hogsmeade and JP first thing in the morning.
We left Hogsmeade about 0740 and were on the ride about 0800. A queue started forming pretty early on after entering JP, but very organized by staff. I don’t know what time they actually starting running the ride, but it was definitely before 0800.
Today and yesterday they EA at 0650.
