My family was there last year over the 4th! It was not bad at all. Most rides during week, maybe 15-20 minute waits. We went to AK during day on the 4th, then crazy me I let them talk me into MK that evening for fireworks! Very crowded! We left after fireworks and they opened a path behind buildings on main street so you didn' have to try to fight crowds on main street! We were at ASMO, bus wait wasn't bad either, they were running lots of extra buses! Fireworks were very nice, I don't think I'll try to watch them from within the park again. Going later in July this year!!
