We have always taken the approach of zigging when everyone else zags. It's worked well for us in the past and continued to work well in October. We'll be there in a few weeks and I'll report back how things go this time.
MK - We head straight to Adventureland. Ride JC and PotC with minimal waits while everyone heads to Fantasyland to get in line for 7DMT.
AK - Safari and then the rest of the park while the masses are all headed to Pandora.
EP - Soarin' - This used to be a conventional wisdom move, but now most people are headed to Frozen and TT first, making Soarin' at RD that much less crowded.
DHS - Galaxy's Edge - Rode MF twice with minimal waits while everyone rushed to MMRR and SDD.
Our method does result in waiting 45-60 minutes for some of those other popular rides, but we found that you wait that long anyway unless you're at the very front of the pack. Heading in a different direction allows us to start our day of by riding a lot more things in the morning and then after lunch when those lines get long from everyone heading there next, we're hitting those few headliners that they were waiting for all morning.
As always, YMMV. If you are at the very front of the pack, heading to MMRR, SDD, FoP, 7DMT, etc. may end up working better for you.
