I guess you have to figure out which parks you want to see in three days, also. If you are doing USO/IOA, do you plan on getting both done in one day or one day each park?
Also, are your kids into thrill rides? You could put off USO/IOA until they are older and focus on WDW. We did USO/IOA with another family this summer and their kids (5 and 8) had not experienced thrill rides and there were a lot of tears and "I'm not going on that" throughout the parks. They enjoyed WDW rides much more. My kids have been on rollercoasters since they were tall enough, so Universal rides were a hoot for them. Just a thought. We spent a lot of time with our friends' kids explaining that Back to the Future was not going to hurt them, etc. It was tough.
Looks like you are including MK and the Studios with CRT and Fantasmic! You could plan Illuminations Cruise on one of the Universal days, along with HHD or Cirque. I, personally, would choose Cirque over HHD, but I am one of the few who did not like HHD. You have three evenings filled with activities, so try to do those on the days that the parks close early.
You could do AK in one morning and hit the Studios in the afternoon and include Fantismic! that night. That gives you a day at MK and another day at Epcot.
Dumb question, but is this during Easter Break? You have to deal with the crowds then with the few days you are going. You should do MK on an Extra Magic Hour day to get Fantasyland done in the morning without long lines. We only use the extra magic hour for MK for our family and find that it works well for Fantasyland and young kids.
Start on day one of your trip to make PS at CRT just in case you don't get through the first day, you have four other days to try for. Work around that if CRT is very important to you.
I know I have not helped with the do not miss, but just wanted to help a little in the planning. Good luck and happy planning!
