Arrived late Saturday night, Nov. 1, but too late to make it into the park and Diagon Alley before they closed for the last
HHN. Debated EE and decided against it for Sunday, Nov. 2 even with an extra hour of sleep. Well, I checked the Universal App as I was getting ready in my CBBR room.
SUNDAY, NOV. 2
8am (EE)
9am (park open): 75 min.
10am: 120 min
11am: 135 min
I set an alert in the Universal App to let me know if it dropped down to 75 min. And sometime around 12:30pm, it actually dropped to 45 min (maybe a glitch in the app?), but quickly went back up to 75 min and stayed around 75 min for the first part of the afternoon. About 3pm, it dropped to 60 min and that's when I finally got in the single rider line.
I went back Monday (today), still deciding against EE, but it wasn't as crowded as Sunday.
MONDAY, NOV. 3
8am (EE)
9am (park open): 60 min.
10am: 75 min
At 11:15am, the wait time dropped to 45 min and I got in the standby line. We were on a ride vehicle in 33 min. I would occasionally check the app before leaving the park at 2pm and it was always at 45 min. I don't know what the wait times were the rest of the day, since I drove down to the Magic Kingdom so I could try their new attraction, Seven Dwarfs Mine Train.
TUESDAY, NOV. 4
Mid-day from 11:30 - 3pm, the wait time was 30 min(!) every time I checked. I rode single rider at 1:30pm and was on a ride vehicle in about 7 minutes.
