Hello Linda! Welcome to the Disney Parks Moms Panel.
Character dining at Walt Disney World Resort is an excellent way of maximizing your time and experiencing fine food and character meets all in one. As far as the "most" characters at a breakfast location on Walt Disney World Resort property, it depends on whether you are looking to hang out with the "Fab 5" or mingle with royalty and Disney Princesses.
At
Chef Mickey's Fun Time Buffet at Disney's Contemporary Resort, you have a chance to savor an all-you-care-to-enjoy buffet while meeting Mickey Mouse, Minnie Mouse, Donald Duck, Goofy and Pluto. There are other locations where you can meet up to 4 characters during breakfast dining, but the only place on property where these 5 get together all at once is Chef Mickey's.
If you would rather spend a morning dining with Disney Princesses, then there are 2 locations that might peak your interest.
Fairytale Dining at Cinderella's Royal Table lets you dine in Cinderella Castle in the heart of the Magic Kingdom while meeting Cinderella and 4 of her Princess friends.
Princess Storybook Dining in Akershus Royal Banquet Hall at Epcot offers an opportunity to meet several Disney Princesses. All character experiences are subject to change.
Walt Disney World Resort
offers many opportunities to dine with all of your favorite characters. My advice to you is to balance convenience as far as timing and location while ensuring that you meet the characters on your "must-see" list when choosing a character dining location.
Bon Appétit and Happy Meets!
