Are PM EMH always 3 hrs?

[hAm53]

everywhere I read about PM EMH it says the park stays open "up to 3 hrs". is there an actual schedule of the times? or is it always 3 hrs. specifically i'm looking for the first two weeks of sept, which i know aren't out yet, but i'm trying to get an idea based on what thye are right now.

As of right now, all EMH in the evenings are 3 hours long, however the schedule of which days for which parks continues to rotate.

I believe I read somewhere tonight that when AK is open exceptionally late anyway (well, for AK) it is only two hours in some of the most recent cast member schedules into the early summer season. I'll have to go look, but I believe when AK is open until 8PM anyway it only stays open until 10PM.

Other than that, so far, all EMH's have been three hours (including when AK is open until 5/6).
