We did not use the EMH. Because we went during 'off' season, they had only one or the other each day and one day they didn't have one at all. If I was a better planner, I would have scheduled our ADR's for the park that had the EMH. It always seemed like the EMH was not convinent for us. I also remember that I read on here that those who did utilize the EMH said that the parks were only crowded during EMH. We made a HUGE mistake by not planning, so congrats-you are a step ahead of us. You should do fine...I am not sure when you are going, but remember that the
MNSSHP draws big crowds in MK, they get there early and stay late.
