Hi...all the parks are celebrating DL 50th..new rides, new shows...I don't really know if anyone truly knows how the crowds are going to be influenced....I've heard people on both sides of the fence....we're going to prepare for the worst and be happily suprised if their wrong. The only definate change I've noticed so far is that on may 5 epcot closes at 3pm....Good Luck and enjoy your trip!
