I think it really depends on what parks on which days. We were also there 9/30 to 10/7. We had a WONDERFUL start to the trip. Great weather all week. No rain at all. Partly cloudy so it wasn't too hot. Every park was walk on for most rides all day. It was just perfect!!!
UNTIL, we went to AK on Friday. What a mistake. Crowds were HUGE and the temps in the 90's and just oppressive. It was a late night EMH and we didn't bother to stay and take advantage of it, it was just too miserable in the afternoon. We all decided the time would be better spent at the hotel pool. I had warned my family it might be crowded due to evening EMH (we usually avoid those) it was just horrible. FPs for Everest were all used up by shortly after 11am!
Our last day was Sat. Originally I planned for us to be at AK that day, but we felt we wanted to have MK as our final taste of this Disney trip. BIG MISTAKE! The park had closed early the last 2 nights for the
MNSSHP. It was planned to be open til midnight that night. We thought we could enjoy the morning and be out by lunchtime and avoid the crowds. WRONG WRONG WRONG. It was crowded from the start. We raced to Space Mtn w/ everyone else and had a 20min wait just to get past the first measuring person outside. They were measuring anyone who was even remotely close to the limit. Fortunately a CM was walking the line and handed us our parent swap pass so dh and dd could race to Fantasyland. They had a short wait for Dumbo and were just coming off Pooh as we approached from having ridden Space Mtn. Peter Pan's line was over 30mins so we grabbed a FP and rode Snow White. The place was just packed w/ people so quickly, and again...a VERY hot in the 90's day! We made good use of FP and parent swap passes we had accumulated that morning and a few days previous. But all were in agreement to bail on the park shortly after noon. We just hung around the hotel pool and play area, ate in the Foodcourt, and shopped until our p/u at 5:30pm.
The day just dragged and was so hot. It really put a damper on what was otherwise a spectacular trip w/ a lot of special CM moments and even a Disney Dream FP for our family!!!!
Bottom line, we will NEVER do MK on a Sat, even if it is just a "clean up day" for a few rides. ESPECIALLY after 2 special park events and early closings. Can you say dumb???!!! Yep, we were. Fortunately Wed at MK was empty and we did a lot of rides early on the MNSSHP Thursday night too so we really were all set for MK. Just should NEVER have gone on Sat. have I said that enough????
As for AK....I think it is a VERY hot park, poor airflow and on a hot day it is brutal. The crowds were up for the holiday weekend and evening EMH. DUMb DUMB DUMB. But again...earlier in the week we made better park choices and never noticed the crowds. It was a wonderful week!
