We were at AK July 16th and thought the crowds were ok. It never felt busy. There were a few big tour groups. Lightning and rain occurred around 3-5pm which really messed up additional FP. We really couldn't get any FP after 4:30 that day.
July 18th we were at MK and through it was very do-able. There were large tour groups in front of the castle prior to rope drop but we mostly avoided them the rest of the day. The only really bad lines were at Jungle Cruise where the wait times were so for off we had to drop out of line after an hour so we could make our Splash FP times. It rained and stormed just prior to the parade which ended up cancelled. We hunkered down for 30 minutes and after that were able to get FP the rest of the night: Small World, Haunted, Pooh, Ariel, Buzz, Jungle Cruise, Carpets. We got to the hub 45 minutes before the fireworks and it was very crowded.
It was a Villains night but I didn't notice them other than a few people costumed up. One mistake we made was exiting after the fireworks. We haven't done that in years and I completely forgot how bad it can be. Main Street was packed and the monorail line took forever packed in like sardines. Next time I will remember to go do a ride or just wait it out.
