Help with EMH planning

[Ratpack]

We like to rise early and get to the parks as early as possible and have really enjoyed EMH in the past. We have an upcoming trip planned for Late June and being the planner I am, started to look at the schedule and plan what parks we would visit each day. I was surprised really to see the park hours posted for June already and I am sure they may change as the time gets closer, but they also had the EMH hours posted. Is it that MK only has one early and one late day each week? I thought maybe it was too early to post EMH, but it appears it is the same schedule this week as it is posted in June. I am guessing they have a set schedule now?
