Today was my youngest son's second Easter, but the first one where he can actually do stuff! We celebrated the resurrection today by going to church, lunch with the grandparents, eating chocolate bunnies, "hunting" for eggs, blowing bubbles and riding in the wagon. The only thing that could have made it better would have been for all of the family to be at Walt Disney World (along with everyone else) celebrating! Easter is one of the busiest times of the year at WDW due to spring break weeks and schools being out for a long weekend. This can be a turn off to some families. If you are willing to brave the crowds, there are lots of exciting things to do at the World that can't be done any other time.
The Easter Bunny and Mrs. Bunny visit kids in the Tour Guide Garden at the Magic Kingdom on Easter and the few days before. On Easter Sunday, 3:00 pm parade at MK will feature an Easter theme. At Epcot there are Easter Egg Hunts for children (ages 3 - 9) every 20 minutes in the Heritage Garden at the American Adventure Pavilion. There are also Egg Relay races for children (ages 6 - 12) from in the Future World West Garden.
I've read in several places online that some of the Resorts do egg hunts and have characters dressed in their Easter Best to meet and greet. There are also special menus for Easter Sunday at some of the restaurants. If you want to start your day off with a worship service, there are Catholic and Protestant services on Disney Property for you to participate in.
