Listen, go at your own pace. It's vacation and it's supposed to be fun! Pardon the pun, but play it by "ear". Of course we all want to get in as much as possible while we are there, but believe me (from experience) staying at a park until midnight, then getting up for an early EMH-makes that day a struggle at times. Do whatever you need to, to have fun and feel energized throughout your vacation. When you see families "freak out" at WDW, it's most likely a by product of trying to do too much on too little sleep.
If it helps you, here is our schedule:
Day One: Arrive at resort around 7pm. Hang out, swim, get a good night of sleep. (hopefully)
Day Two: Up at the crack of dawn for early EMH. This day we plan to go ALL day, no break since it is our first day and we can't help ourselves.
Day Two: At rope drop for a non EMH park. Take a mid-day break. Return for Mickey's NSS Halloween Party until midnight.
Day Three: Relaxing morning at resort. Afternoon park of choice. Dinner at DTD. Shopping. Resort by 11.
Day Four: Rope drop at non EMH park. This is our DHS day, and since we only have a select few things we like here and it's not a Fantasmic night, we will head back for a midday break then to dinner at the Grand Floridian, followed by evening EMH at MK.
Day Five: Rope drop for an AM EMH park. This is AK and we only have a select few attractions we like here so it will be another midday break day (not a long one) then back to Epcot for EMH
Day Six: Early morning breakfast and just hopping around to various parks to get in our "last licks" before leaving at 3pm.
I hope that helps somewhat. Just do what works for your family! And if what you planned isn't working, adapt and have fun! Good luck!!
