This was in May 2007. Not sure if crowds had anything to do with it, but being as I was the trip planner, I did the backtracking to obtain fastpasses:
Animal Kingdom: 13.5
Disney-MGM studios: 13.5
Epcot: 13.5
And the Mac Daddy: Magic Kingdom: 16.5
We were there when they let us in for our PS at Crystal palace at 8am. Many hours and miles later with sore feet on the bus at 1030pm at night.
I was amazed at the overwhelming choice of footgear: the common flip-flop!
