We have been to WDW 4 times at Easter and this last time, 4/13 - 4/21 at POR, during spring break. We have no choice, as we are tied to the schools schedule and cannot go in the summer. It is crowded, but not unbearable at all. Having said that, keep in mind that I am talking about getting to the parks at or right near opening. Incredibly (to us) we have found that the crowds, even at Easter and spring break times, don't start to really pick up until noon or even 1:00pm. We still don't get why so many people start their days at the parks so late, but it works for us! haha We (DH, DW, DD9, DD13) love it from opening until about 1:00pm and are able to get on or into just about anything we want with very little wait time. We also use fast pass as efficiently as possible and double our pleasure on the really crowded rides (Soarin', EE, Test Track, RNRC, Space & Splash Mountain, etc.). So we go from opening to about 1:00pm, have a 1:00pm-2:00pm-ish ADR at whatever park we are at that day, after which we head back to our resort to swim, relax, shop, whatever, for a couple of hours, then regroup and head back to a park or DTD in the evning for however long we want. It works great for us every time. Enjoy.
