We plan on neither on our upcoming trip. The regular park hours are enough for us. No one in my crew is able to get up in time for EMH and feel happy about it. They are on vacation after all. We tried e-ride night on our last trip, but we were able to go the night before we left for home. Our flight was late enough so that we could sleep in. On this trip we want to go to PI on the nights before sleep late days.
With two small children you might want to try MK EMH, if your kids are morning people. We always plan two days for MK and don't have any trouble getting Fantasyland covered by going there first thing one of those days.
