We stayed at Fort Wilderness from the Saturday before Easter until the Saturday after Easter (3/22-29). There's no doubt that WDW is crowded during Easter week!! It's manageable, though. We had our ADRs made well in advance and went to the parks early before it got too crowded. Rides that we didn't wait at all for had 2 hour lines later in the day! I know a lot of the resorts have special easter activities, and I think some of the parks (epcot?) do as well, but we went to AK on Easter and didn't notice anything special there. The weather was decent - it rained some the day we arrived and the day we left, and the beginning of the week was a bit chillier than I'd like, but overall no complaints about the weather. One thing to keep in mind is that Easter was early this year, and it's back into April next year. We always go to WDW the last week of March because that's when our spring break is, and the last week of March is more crowded than usual when Easter falls then. I don't know if Easter week is more or less crowded when it's in March than when it's in April, though, as we've never been for an April Easter.
