Hi Debora!
Congratulations on your upcoming trip to
Walt Disney World in April! It sounds like you love meeting the characters as much as I do! It's one of the most fun things to do at the parks. Currently
Moana is greeting guests at Disney's Hollywood Studios inside the Walt Disney: One Man's Dream attraction, however the characters greeting at this location change frequently, so this could change soon.
You can
meet Anna and Elsa at Royal Sommerhus at Epcot near the new
Frozen Ever After attraction. Olaf does not conduct meet n greets.
Sophia the First and other Disney Junior Pals conduct their meet n greet at Disney's Hollywood Studios in the Animation Courtyard.
You can see a statue of Nemo, Dory and Marlin outside the
Seas with Nemo and Friends at Epcot and take your picture in front of the beautifully decorated backdrop.
I highly suggest checking the
My Disney Experience app the day you arrive to see what characters are greeting, where and at what time. You can also ask a Cast Member to call the Character Hotline when you arrive to get the scoop on what characters are greeting that day and where they are located.
Magically,
Stacy
