We just got back from WDW May 29-June 5, and the crowds didn't seem too bad then. The two busiest times we went were Saturday night at the MK (spent the day at Epcot then hopped over for Spectromagic and fireworks), and Tuesday when we did EE at Disney-MGM, it got so crowded by noon that we hopped over to Epcot. However, we went back to MGM the next day, and the crowds were no problem at all.
