We just returned. Did EMH at Epcot and MK (Thursday). Would definately do those two again- got to ride lots before park regular opening (Fantasyland/Tomorrowland in MK; M:S and TestTrack in Epcot), then went on to pretty empty park areas when the park opened for all. When Mk got crowded (Splash and BTMRR 20 min waits!) went to shows, had a sit down lunch, etc.
