Starting early November, Anna and her sister Elsa will be appearing at both Disneyland and Disney World. They will appear in Fantasyland at Disneyland and at the Norway pavilion at Epcot. According to the official Disney Parks Blog, other Frozen characters are not presently scheduled for meet and greets in the parks.
If they add more characters, I’d like to see Olaf. I think he’d be super cute. Who would you like to see?
