Hello Loretta, thanks for visiting us here at the Disney Parks Moms Panel.
Character dining is available for breakfast, lunch and dinner depending on which Walt Disney World restaurant you choose to dine at. Tusker House, at Disney's Animal Kingdom, is one of my favorite character breakfast locations. There you will get to meet Donald Duck, Daisy Duck, Mickey Mouse and Goofy while dining on a great breakfast of African inspired dishes with some classic American fare as well. Another great character breakfast is Cape May Cafe. At Cape May Cafe you can dine with Goofy, Minnie Mouse and Donald Duck in their pool/beach gear. These pictures are really cute because the characters are in a different outfit than you can see at the parks. For lunch you can dine with Princesses at Cinderella's Royal Table or Disney Jr. characters at Hollywood & Vine. Character dinners can be found at several restaurants including 1900 Park Fare where you can visit with Cinderella and friends and Garden Grill at Epcot with Mickey Mouse, Pluto, Chip and Dale. There are many other character meals found at Walt Disney World and I have linked the
character meal list so you can check them out.
You will be able to meet
Buzz Lightyear and Woody at Pixar Place in Disney's Hollywood Studios. The set where you take pictures with the characters is a lot of fun and the pictures always turn out great. It is one of my favorite meet and greets. You can also find Buzz Lightyear in Tomorrowland at Disney's Magic Kingdom Park. Normally, he can be found not too far from Star Command Headquarters (Buzz Lightyear's Space Ranger Spin) signing autographs and posing for pictures.
Have a great day!
