My DH and I have been to WDW twice, but we are taking the kids for their 1st trip in a couple of weeks (they are DS7 and DD9 - not too far off yours!). Here is how we plan to break it down.
Arrival evening - ADR at 1900 PF - then to DTD for a couple of hours
Day 1 - Epcot WS from AM EMH open to Illuminations close (we will actually start off with some of the FW stuff that opens early, then move to WS as soon as it opens)
Day 2 - AK from open till done. They have PM EMH that day, but will probably leave and go to DTD for a few hours that evening.
Day 3 - MK from AM EMH to close after Wishes. Will probably concentrate most of this day on shows, characters, parades, etc if the weather is nice since we will be back on other days. I'd hate to skip a parade the 1st day if it's nice out, then have them cancelled the other days due to weather or something. We'll do rides too, but Cinderellabration and Mickey's country house are closing during our stay, so we gotta make sure and catch those!
Day 4 - Epcot FW. Will get there after opening due to ADR and 1900 PF for breakfast, but will spend the day mostly in FW unless there are any street acts in WS that we missed the 1st day that we want to try and catch.
Day 5 - MGM for a few hours in the AM for EMH. Lunch at 50's prime time then back to hotel to rest/hit the pool. HDDR and Electric Water Pageant that night at FW
Day 6 - Typhoon Lagoon till we're done. Then over to MK if time for PM EMH till we get tired or they close!
Day 7 - MGM from open to Fantasmic close
Day 8 - Blizzard Beach from open till we are done - then to Disney Quest.
Day 9 & 10 will split between the 4 parks re-doing favorites. Left ADR's open for these days as our TS credits will all be used up (CRT and HDDR take 2 each), so we can wing it. Each day has 1 EMH, so will probably factor that into where we go and when but will probably go Day 9 am AK/pm MK and Day 10 am MGM/pm Epcot. That will change if there were fireworks or parades/ entertainers that were rained out on earlier visits that we want to see.
We have made all our ADR's so we don't have to do a lot of park hopping to eat. If we don't need a lot of time for re-do's at the end, we may try and catch the campfire and movie at FW one of those last 2 nights.
Day 11 - Depart early am for trip home

I'm missing it already and I haven't even gotten there yet!!
