I took my wife and two kids to WDW two years ago over Easter. Everything I read said this was one of the busiest times of the year. Well, there's no doubt it was busy. But my DW and I were just thrilled with how nice it was to be in Disney World when it wasn't so hot. The weather was so much more comfortable than June or July when we typically would go, that it didn't matter that the parks were a little crowded or that we had to wait in some lines.
We took advantage of the early morning and evening extra magic hours, weren't commando (trying to pack every possible activity in), and were prepared for crowds so that we didn't get upset when we found them.
In the end, we both agreed that it wasn't nearly as busy as we had prepared ourselves for. The weather was so much better, too.
We're going back again in two weeks for another Easter trip. Hoping that we'll be just as pleased as we were last time. Hope you enjoy your trip next year.
