Hi Andrea,
Well, let the royal fun begin as your daughter will have lots of fun opportunities to relish in all there is available for little princesses.
Consider getting a dining reservation at either
Cinderella's Royal Table in Magic Kingdom or
Akershus Royal Banquet Hall in Norway at Epcot. Both of these locations offer breakfast, lunch and dinner dining with several princesses. Keep in mind that these reservations are very popular, so you will want to try to get a reservation as soon as possible as both of these tend to book up and reservations can be made up to 180 days out.
Next, be sure to visit
Princess Fairytale Hall in Magic Kingdom to meet princesses for a photo opportunity and autographs. You can also usually find many princesses in their "native" countries for meet and greets in World Showcase in Epcot. For example, Belle can usually be found in France, Mulan in China, and Jasmine in Morocco.
An absolute must-do for your tiny princess would be
Enchanted Tales with Belle. This interactive storytelling with Belle will offer an unique experience that you will remember forever. Other attractions and rides are Under the Sea - Journey of the Little Mermaid in Magic Kingdom and Beauty and the Beast - Live on Stage at Disney's Hollywood Studios. Lastly, the brand new Festival of Fantasy Parade at Magic Kingdom with scenes and character from many beloved Disney princesses is sure to delight and amuse!
I hope she has the most regal time creating memories that will last a lifetime.
