EMH visitors fall into a couple of category's. One, they get there for opening, stay till about noon and hop over to another park. 2 the ones that plan on getting to EMH but end up getting their about the normal opening time. If you plan your day, EMH can be just like any other day at the park. Just know the 1st time people will uselessly be the ones at the park with EMH, that is why I avoid it if I can.
