Easter is March 27th. The week before and the week after Easter are always the most crowded, however, Spring Breaks are spread out through March and April. When we lived in Florida we always got Good Friday and then the week after Easter off. Here we always get the last week of March no matter when Easter is. We went to WDW last March. It was a couple of weeks before Easter and crowds were moderate, not too bad to me. I would avoid the weeks around Easter, but the others are not too bad IMO.
