Park closing at USF and IOA during this holiday week range anywhere from 8:00pm to 10:00pm during the Thanksgiving week. Except 11/24, when USF closes at 6:00pm. 
Curiosity got the best of me and despite searching, I can’t figure out why. Is there a special event or something?
They often do Private Groups Sales events when closing early for companies. I can’t verify it for this date as they don’t publish their group sales calendar. (most parks don’t)
I love UOR, but their closing hours are dumb at times. Closing at 7pm the entire week in December I was trying to go is part of why I didn’t try harder to keep my plans.
Yeah I’m a little surprised by their closing times. They just recently bumped IOA closing from 8:00 to 9:00 that week. I would think 10:00pm would be the standard for a full holiday week, but 9:00 is reasonable.
The 6:00pm for USF though is a head scratcher. Even if there is some sort of private group, I’m surprised they allow it during a holiday week.
It’s pretty rare that UOR stays up until 10pm. It really is only at the busiest times. 8pm / 9pm is normal in the summer though…
I’ve seen it a few times. I imagine these groups pay a high premium for it!
