You don't say exactly when you are going, but if there is a chance it will be crowded, I say go early, even if you miss the opening ceremony. This was our first experience with EMH or EE or whatever you want to call it, at MK. In the past we have always gone to a different park to avoid the crowds. Well I don't know if it was because MK opened at 7 am, but I couldn't believe how much we got done. I am now a believer. One morning we did all of Fantasy Land, one all of Tomorrowland, and both days we were at the rope drop for Frontierland. Did Splash M and BTMRR, then over to WALK on Aladdin's Carpets, Pirates and Jungle Cruise. Plus we got fastpasses for something we wanted to do again- one day Splash one day Space M. And it was Easter Week! JMHO.
