You’re supposed to take it SLOW if you have 11 days!
We always have a minimum of 10 and up to 21. Never ever rope dropped, and rarely go all day anywhere. Usually start at 10 or 11, stay until we’re tired, which varies from person to person, then return to resort to chill out, and sometimes some of us will return later.
We also have offsite days, Kennedy for sure, Universal sometimes, shopping, Legoland, airboats …
But back to OP. I would give yourself two full afternoons for World Showcase.
And 2 decent half days at DHS. Don’t miss Indy amongst the shows, it’s the last remnant of a movie making heritage left, and stands up well after all the years. If you like Star Wars, don’t miss the March of the First Order - great fun.
AK to me has the best theming of all the parks. Take time to look around Harambe, look up and listen for the sound-track. Watch the drummers, count the carvings around the Tree of Life, see the Tree of Life awakenings and the night time entertainment. And don’t forget the baby tigers, and swimming hippos along the Gorilla Trail.
So if you’re not going offsite, then I would do 3 days MK, 2 or 3 at Epcot, 2 at DHS, 2 at AK. But not all rope drop to end. Mix up late starts with pool time, and then earlier starts and either a break or evenings at the Boardwalk, Monorail resorts, Resort hopping (GF, WL, AKL, Boardwalk resorts, Poly).
