I went Sept 28 - Oct 6. Our itinerary was as follows:
Sept 28- check in and hang out at Kidani
Sept 29- MK in the morning and AK at nightt
Sept 30- HS EEMH, then Skyliner over to Epcot then back to pool and Epcot for last Illuminations show (HS was really busy that morning for EEMH and Epcot was busy due to the last show but that was expected.)
Oct 1- TL in the morning and
MNSSHP at night (first and last party. It was way too crowded and didn't justify the upcharge cost in my mind)
Oct 2 - AK in the morning, was supposed to do MK at night but before we left we check the wait times and they were insane (probably because MK was only open at night 3 nights this week due to 4 MNSSHP nights) so instead we went to HS and almost everything was walk on or very low lines.
Oct 3 - MK in the morning and Epcot at night (Epcot was really busy)
Oct 4 - HS in the morning and Epcot at night (Epcot was insanely busy, so we left and went to DS) (there were a ton of cars coming into the park at 6:30 at night)
Oct 5 - Sea World and DS
Oct 6 - pool and departure
I pushed my family to get the most out of this vacation and the heat and humidity didn't help but i'm proud of them. My 3 and 6 y/o did better than my wife (she prefers beach vacation where we don't do anything but I reminded her that the beach vacation is in 8 months and I'll be the one complaining because I don't like just laying around on the beach)
It seems as though there was a herd of people that all had the exact same itinerary. We followed all of our FP's of course but then at night I would suggest that everyone follows
MDE to see where the crowds are and avoid that park. AK and HS were really slow at night almost everynight.
The weather was hot and it didn't really rain other than Monday night and Sunday morning. Overall the crowds weren't bad, just had to avoid that herd.
I only had one run in with other people... We were in the Kali River line and had been waiting a while. I went on the MDE App and noticed that a fast pass had just opened up so I picked up that FP and switched over to the FP line and everyone thought I was cutting the line. So they all got mad at my family and I but then I think they realized what happened when I was able to get in through the FP scanner. Moral of the story....Don't get mad at the people who are better at using the FP system.
