we went around may 27-june 10 last few years and during the july 4 weekend the few years before that pros and cons:
may 27-june 10-
pros-less crowds except memorial day, great weather even though it rained everyday at around 4, easy to get ps at restaurants. Did I mention less crowds, also STAR Wars weekend is during this time at MGM which is really fun.
cons-hours are quite short during this time, I cannot remember but there were times MK closed at 7-8pm and AK at 5pm,etc. Thats about it.
July 4-14
pros-everything is open late, great fireworks celebration at MK
cons-crowded oh boy, real crowded!!, hot and HUMID, oh my gosh, I cannot believe how humid especially at Animal Kingdom, hard to get ps at restaurants unless you do it in advance(forget last minute at popular places).
Dont get me wrong, it is real fun to be there during July 4 weekend but I much prefer late May early June.
Have fun
