What is the usual schedule for the evening EMH so far? 1-3 hours after the park closes is a bit vague and I suspect that 1 hour in AK may be all because of the animals.
EMH are one hour before opening in the morning or 3 hours after closing at night.There's not much more to it than that! Here's a link to more info we have at the DIS on rides that are open and the park schedules for March,April and May for EMH: http://www.wdwinfo.com/wdwinfo/earlyentry.htm
