Our kids (DD4 & DS3) are early risers, so I am building EMH into our itinerary. Unlike yours, however, our kids do not like to sleep in their strollers, so we'll be going back to our room for afternoon breaks and/or naps. We are also in a condo. so we'll be eating breakfast in our room. The kids are normally up between 6:30-7:00, so we'll get ready, eat breakfast and then head out to the EMH park. We'll stay there until late morning then head back to the room for lunch. After lunch, we'll have some down time before hopping to a different park in the afternoon/evening. Ultimately, given the time of year you're traveling, if you're going to spend the full day at the parks and this won't have an adverse impact on your kids you probably won't really need to do EMH tp experience all of the attractions you want.
