Yeah. I starting to wonder if everyone checks the calendars, sees that a day should be light and decides to go that day. Making it way worse than projected. Maybe we should try the days predicted to be heavy.
This what I've been saying for a long time! These "crowd calendars" are making people think their is an off-season at WDW, which, is taking away the off-season. It used to be that you could go in September and the place was dead, now it's as busy as almost any other time because people think they have knowledge everyone else doesn't.
To the OP, I've been in Sept. years ago (when it was dead) and I've been in summer/spring break when it's nuts... a busy day at WDW beats any day at work When it's busy you just have to plan a little more; early mornings, late nights, etc. It's still manageable and it's still fun!
