Everyone will probably tell you, it depends on your children.. Which is so very true! It sounds like you are in the same boat as my family was our last trip, with younger ones and meeting characters being a priority. On our last trip we spent the most time at Magic kingdom, then DHS, then AK and then Epcot. Epcot does have a good amount of characters but most being princesses, but other then that for your ages of your kids there isn't so much for them unless. The world showcase IMO is more for teens and adults, my daughter only enjoyed nemo and turtle talk at Epcot and meeting Mickey and friends at character spot which of who you could meet at MK also. So needless to say our family will be skipping Epcot next time or atleast only doing a night there. Now that's just my family. For our kids and ages, tastes, etc., MK and DHS were the best options and AK was right up there also because our kids love zoos and animals so Ak having that and Disney all in one park was great. We picked more days at MK and DHS Only because our kids enjoy fantasy land because they are young (3-7) and it had the most for them, they enjoyed meeting the characters at MK also. DHS was the second best because they all enjoy Disney junior still and the shows at DHS were very entertaining for them.. (Little mermaid, fantastic, Indiana jones, car stunt show). If I were you I would do 3 days at MK, 1 at DHS and 1 at AK But again it all depends on the taste of your kids style to the parks. Many people I've noticed on these boards say they would never skip Epcot but for us it's a definite skip, our kids are just too young to enjoy that park really for what it is or even at all.
