With kids that age...The day you plan on Going to MK Go to Fantasyland first (if you're getting there when park opens) thats the least crowded time.
Oh and I you want a really good breakfast...Ohana @ the Poly is worth doing
A great dinner show Is the Hoop de doo..
Its an all you can eat BBQ Ribs and Fried Chicken etc...
In MK there is a sit down called the Plaza Resturant...Food is excellent and Is truely best bang for your buck foodwise
In Epcot..Drinking around the wold is a must..
I also like to end my day there @ La Hacinda de San Angel getting a seat near window in order to watch Illuminations
