Our first and only trip was the last week of September, 2002. The crowds were great on Wed, Thurs, Fri.
On Saturday, the morning started out alright, but by noon, Fantasyland was packed. Fastpass for Peter Pan and Winnie the Pooh were soldout for the day by about 2:00PM. Lines at concessions were much longer than anything we had seen during the week. We will stay away from MK on Saturdays from now on. (Except at night to see Spectromagic; this is a do-not-miss)
