We were at WDW for the two weeks after Easter in 2014 and found no problems with the crowds. It was most crowded the first week after the holiday and the crowds thinned out as the week wore on. However the crowds were nothing like the horror photos we'd been seeing from folks at the parks the week before Easter Sunday (shoulder to shoulder crowds). The following week was a breeze for us. Still plenty of people, but not so crowded you were sorry you were there, lol.
Easter was very late that year (end of April, a lot of schools had long since taken their breaks) and that could have been part of the reason why it wasn't insanely busy. I'd try another trip the week after Easter if the kids had it off school.
