Grade Nights?

[labdogs42]

I'm helping my SIL plan a trip for May 7-14 and I see that the MK closes at 7pm on the 7th because of grad night. Is that right? It also says that Wishes is at 10pm, but the park will be closed then, right? What's the deal? I need to tell her where to make ADR's for that day and I guess I'll steer away from the Magic Kingdom based on this info. Is that right?

Duh, grad nights. And I meant to post this on Theme Parks. Sorry guys, my brain must not work today! Hopefully someone here can answer this anyway!
