Wow,
Sounds like a great trip! You have a nice looking family!
Do you mind if I make some suggestions?
1. Only do EMH if you can be there when EMH starts. If your kids are early birds, then great, go and enjoy! If you believe you will get there 30 to 45 minutes into EMH you may not be as happy.
2. DHS: if you leave AK at 2:30 there is no direct park to park bus, you will need to transfer at a resort or the TTC so it is likely it will take an hour or more to get to DHS and in the door - so you'll definitely miss the parade. Also it is almost assured that the FPs will be GONE by 3:30 pm on a Star Wars Weekend day and a Fantasmic night. DHS will be absolutely MOBBED!!!!! It is likely that all FPs for TSMM will be gone before 12 noon and wait times will be over an hour. Now, if you love star wars and want to see the ambiance, and can resign yourself to Playhouse Disney-Live on Stage!, *The Voyage of the Little Mermaid, The Magic of Disney Animation, Beauty and The Beast-Live on Stage! you should be OK you could probably add muppets too. If Fantasmic is only showing once that night you may want to plan to be on line 60 -75 minutes before the show starts (please see Robo's post about this, it is the best!)
3. You won't be able to do everything or even half. Breathe, relax. It is more important you enjoy what you do. Make sure you prioritize your days and follow some sort of plan (whether easywdw.com (free), touringplans.com (or the book The Unofficial Guide to Walt Disney World), or TourGuide Mike) to help you do rides that develop long lines first before there are lines, you can do a lot more and be much less frazzled.
4. Do you have reservations for your meals?
I hope this didn't come across as critical, because I didn't mean it that way: I was a newbie too last year! I didn't want you to be horribly shocked when you found you couldn't do what you wanted.
If you like - you can post your itinerary on the Parks board and see what others think. It is possible to move ADRs at this point. I just had to redo all of mine when we added another person to our trip.
Best wishes.
