Since it is the slow season, the MK parades and fireworks sometimes only go on Saturday night, making MK really crowded. Try to avoid this if you can.
We will be there, and are planning EE on Saturday in MGM, then back to our resort for a "resort" night - pool (if warm enough), arcade, shopping, animals (AKL), and dinner at Boma.
Sunday we're going to try AK, and Sunday night the kids will go to Simba's Cubhouse (they love hanging with kids from all over the place!).
Monday we're going to try DisneyQuest or Blizzard Beach (if we get a warm day). Then Epcot in the evening, as the crowds will start to calm down.
We will be there two days before and two days after MLK weekend, so we'll get all the parks then. Yeah, we're pulling the kids out of school. Naughty parents!
