This will be our 5th trip during early June -- the last three visits have been during the first two weeks. We have found that the crowds are very manageable--it will be more crowded than some times of the year but less crowded than it gets later in the summer. Getting to the parks early and FastPass are the best ways to handle the crowd. We have usually been able to see and do everything we wanted to during this time of year. For us, the most challenging experience is seeing Spectromagic and Wishes--we usually stake out a spot 2 hours in advance.
