Hi Cathy,
Thank you for visiting the Disney Parks Moms Panel with your question. There are many ways to see characters at Walt Disney World. From parades and shows to opportunities to
dine with characters, there is something for everyone!
The characters do not all appear at any one theme park; rather, they are located at all of the theme parks. Some characters are only at one theme park, while you might find others at multiple theme parks. The following links will give character and entertainment activities at each of the four theme parks:
Magic Kingdom,
Epcot,
Disney's Hollywood Studios, and
Disney's Animal Kingdom. For character interaction, look for the descriptions that say "Meet" at the beginning of the description.
Overall, I think that Magic Kingdom has the most opportunities to see and interact with characters. Along with the meetings and numerous dining opportunities, there are wonderful parades and experiences such as the
Festival of Fantasy Parade and the
Move it! Shake it! Dance & Play It! Street Party at which you can see and dance along with many Disney and Pixar characters.
I hope that these thoughts are helpful for you, Cathy! Please do let us know if you have any further questions.
