We are here now and it is storming like mad. We are riding it out in our room but really want to just bite the bullet and get into the gringotts line tonight to get it done (we just arrived and don't want to get up at 4am for a ride)
We'll be there when the parks close at 9pm, so does it look like they close it 3 hours before park closing or does the closing time depend on how busy the park is that day?
I think it's usually based off the wait time. If it's more than 3 hours then it'll be closed before 7. I've seen it closed off at 7 and also closed off as late as 8.
