Traveled with DD 5.5 and DD 2.
Playhouse Disney should be first, for they don't offer fastpass and it is a very popular show. Very limited seating for most folks sit on the floor with their kids.
Check to see if Lilo and Stitch are available. They stand in the courtyard of the Disney Animation attraction, which is close to Playhouse Disney. I had to ask a CM where they were, but it is a nice setup if your kids are Lilo and Stitch fans.
Voyage of the Little Mermaid. Close to Playhouse Disney and crowded as well. You can fastpass if you want.
Great Movie Ride or Millionaire. The kids liked that one too.
Muppetvision. Gotta love Fozzie and his cheap 3D tricks. This puts you way in the back of the place. Pizza planet and ABC Commisionary are fairly close by. Work your way toward the front after that. Muppetvision 3D wasn't too crowded.
We did a lot of criss crossing, but the park isn't too bad to move around in.
A lot of characters congregate along the Sorcerer's Hat. Lilo and Stitch are back by the Disney Animation Attraction.
