To all those who are still waiting and watching castles, orbits, and millennium falcons...have patience.
I first tried yesterday at midnight.
I then got up at 7 and tried for almost 2 hours. I did some work, then tried again at 12.
I got more castles and more orbits. I read through the thread and tried the dining reservation workaround and got the millennium falcon. I sat waiting for 2 hours and then did some laundry while checking on my three tabs (two in chrome, one in incognito chrome).
After another hour or so, I noticed one tab go to a blue screen behind another tab I was working on. I quickly hit it, logged in, and was able to get my park reservations for early September 2020 at around 5 pm.
Hang in there, it will work!
