We went the last week of October last year. The weather was great, it wasn't crazy hot like when we normally go in August, but was still hot enough that swimming was nice. The weekdays weren't too busy, but our last Saturday at Magic Kingdom was crazy busy. It was also the first week of Genie and we did not get the
genie+. I did pay for us to ride Rise of the Resistance, Flight of Passage and 7Dwarves. Rise, we have gotten to the park early enough but went to do Slinky first and by the time we got over there it was crazy, then it kept breaking down. FOP we got the park late, so missed the shorter line and didn't want to miss it. 7D we did on our last night because it's one of my favs and while we'd been able to ride Splash and Big Thunder multiple times, 7D had a long line the whole time. We had a nice trip, it flew by. We didn't go to the after hours party they had last year, by the time I booked my trip it was sold out, but I have done
MNSSHP a few times and we love it. But we love it for the short lines on rides, and don't do the extra characters.
For flights, they seem to change a lot unfortunately. I am not sure if they are starting to stabilize yet or not and just keep hearing horror stories about flying. We normally fly Air Canada because we're in Ottawa and no one else seems to offer direct flights but even they keep changing us to having to connect in Toronto or Montreal. Makes for a long day in a mask (was over 12 hours coming home last October, needed it on the bus to MCO which was 4 hours before the flight, and just a long day). I am not sure those mandates have changed yet.
Enjoy your trip, and the planning
