Hi Sian,
Congratulations on booking your family's first Walt Disney World vacation! Easter at Walt Disney World is a "hopping" good time. The official schedule for Easter 2015 has not been fully released, but should be soon.
Most of the resorts will have special activities like egg hunts, fun dance parties, and crafts. You'll receive a schedule of resort events when you check in to your resort.
In Epcot, you can join in the
Egg-Stravaganza. You can purchase a special map and stickers for $4.95. Explore Epcot and look for the hidden eggs. After you find all of the eggs, return your map to Port of Entry for a special surprise!
Don't forget to stop by and see the Easter Bunny at Magic Kingdom Park, too. Check the Times Guide for specific meeting times and locations.
Please let us know if you have any other questions, Sian. I know you'll have a most magical vacation.
Have a Disney day,
Ashley
