We like to do the early EMH at MK. We'll sometimes do it at AK. With the addition of TSL at HS, we'll probably do one there. We'll do EP if it fits into the schedule. We always hop to another park around lunch time on the days we do early EMH.
However, I know my family will get up and get there. There are lots of people who plan to do the early EMH, but then they can't get everyone up, ready and out the door in time. With FP+, you're sort of locked in to that park whether you get there for the early hour or not, so be sure you're family will get out of bed before you decide to utilize the early EMH.
If your family are night-owls, then do the reverse and hop to the late EMH park. I think the early EMH hours are less crowded than the late, but others love them.
One last suggestion: Keep the plan you have now, but also make one utilizing your EMH of choice. The ADRs you're able to get may make the choice for you. However, don't set that schedule in stone even then. When it comes time for FP+, you may need to make adjustments again depending on what you can get for those.
