From the Official Disney Parks Blog…
For one week only, from March 18-24, you’ll be able to search for special hidden “eggs” themed to Disney characters at Epcot and at Disney California Adventure park and then record your discoveries on specially themed Eggs-perience park maps.
At Epcot, maps can be purchased at the Heritage Manor in the American Adventure Pavilion, International Gateway, Pin Central and Port of Entry.
And at Disney California Adventure park, you can purchase the map at Elias & Co., Oswald’s, Radiator Springs Curios, Tower Hotel Gifts and Treasures in Paradise.
Each map and set of stickers will cost $4.95, plus tax at select locations. And whether you choose to hunt for eggs or not, return your map to a Port of Entry at Epcot or Elias & Co. at Disney California Adventure park for a surprise.
