Hi Brandy,
Thank you so much for visiting the Disney Parks Moms Panel with your question!
There are great character meet and greet opportunities in all four Walt Disney World theme parks. Here are lists of entertainment and character meetings at
Magic Kingdom,
Epcot,
Disney's Hollywood Studios, and
Disney's Animal Kingdom. As you can see, you can meet Mickey Mouse and Minnie Mouse in each theme park! They will be in different outfits in each theme park. There are also different princesses at the various theme parks, so you can check the links that I provided for which princesses are at each park. Magic Kingdom is a great option, with Princess Fairytale Hall hosting many princesses.
Another wonderful choice for meeting characters is at a
character dining experience. At Chef Mickey's at Disney's Contemporary Resort, you can meet Mickey Mouse and his friends in their chef outfits. To meet the princesses, head to either Cinderella's Royal Table at Magic Kingdom or Akershus Royal Banquet Hall in Epcot. These experiences are delightful and enchanting. I have a wonderful picture of my daughter when she was a toddler with her grandfather and Belle at Akershus Royal Banquet Hall. It is truly a treasured memory. As character dining experiences are very popular, I suggest that you make reservations for these soon.
Please do be aware that all character appearances are subject to change.
I hope that this information is helpful for you, Brandy! Please do let us know if you have any further questions.
