I know this is standard advice, to keep hard to get fast passes. As a counterpoint for consideration, I find with small children in a party, one of the primary benefits of EMM is getting a lot done without having to spend a full day in the parks. Getting all of the FantasyLand rides in early, then heading straight to HM/BTMR at Rope Drop, then using FPs for say Splash, Pirates and Jungle Cruise, while filling in a few rides/shows (Hall of Predients/Tiki/Country Bears) between FPs means you can tour more than half the park at a fairly relaxed pace without having waited on a single line, spend some downtime at shows in the AC, and be back to the resort by 2:00-3:00.
Whichever way you go, you can't go wrong - enjoy!
