Does US ever extend their hours?

[Tay N Evie's Mom]

We're going to US Nov 5-10 for the Veteran's Day Holiday. I was looking over US/IOA hours and they're kind of short. Do they ever extend their hours if they see larger crowds or is what they've posted etched in stone?

It's usually etched in stone on the closing hours. They want everyone going to City Walk to eat dinner.
The opening time is the one that varies. On extremely busy days, the park will open half an hour early at 08:30am.
During the summer, it was 08:45am.

In your case, the opening time is 10am. You wanna be standing at the gate by 09:30am, so you're near the front.

That will get you a lap of walkon rides before the crowd arrives at 11am. You'll have plenty of time to see everything, and by 7pm, you'll be ready for dinner.
