We go to Disney when it works for our real-life schedule, and I use logic & knowledge from my own experience in planning what to do when we're there.
I've studied & counted on crowd calendars in the past and been burned by them- am so done with that. The year-round crowds are reaching the point that crowd calendars have much less value than they used to. The important thing is knowing how to tour effectively, and I don't need a computer to plan that for me.
It's liberating to go whenever & wherever works for us, without relying on "experts" to give us wrong advice. It's kind of like being on vacation.
