Hi Laurie,
I am a huge character dining fan, and I try to experience as many as possible during each vacation. I have found that two character dining experiences in one day is plenty for my young daughter, I would suggest possibly reducing your number down to two, and perhaps schedule a breakfast on another day.
My top
character dining experience is hands down Chef Mickey's located at Disney's Contemporary Resort. Here you will dine with Mickey and the Gang, while enjoying an all you care to eat buffet. For your princess loving daughter, I would recommend Cinderella's Happily Ever After Dinner at 1900 Park Fare inside of Disney's Grand Floridian Resort and Spa. This is also an all you care to eat buffet with is hosted by Cinderella and Prince Charming! The stepsisters and Lady Tremaine are also in attendance. Another great option would also be breakfast at 'Ohana located at Disney's Polynesian Resort. This is an all you care to eat Family style meal where Lilo, Stitch, Mickey and Pluto greet guests.
Now inside a theme park, I would recommend dining at Cinderella's Royal Table or Akershus Royal Banquet Hall. Both locations offer a fabulous experience where several Disney Princesses are available to meet and greet throughout your meal. The Crystal Palace at Magic Kingdom is a great buffet with Winnie the Pooh and Friends while Tusker House at Disney's Animal Kingdom also offers a fabulous character dining experience. Please keep in mind that these locations require a valid theme park admission.
Please let me know if you have any other questions Laurie. I would be happy to help you plan the most magical experience possible for you and your family!
