Hi, Veronica! There are currently several restaurants that offer dining opportunities with princesses, but they are really very popular. They can book entirely within days of a 180 day advanced dining reservation window. Cinderella's Royal Table at the Magic Kingdom, Princess Storybook Dining at Restaurant Akershus in EPCOT's World Showcase, or even 1900 Park Fare at dinner all feature princesses in some form or another. You can check availability at any of these restaurants by visiting
Disney World Dining Reservations.
There are princesses as well throughout the theme parks. Your daughter will be able to meet some of her favorites, have her photo taken with them, or even have them autograph something for her. You may find you get some of the most spontaneous reactions from your daughter when you meet the princesses this way!
You can check with a cast member when you arrive or consult the times guide to see where your daughter's favorites can be found. And don't miss the show in the castle forecourt. You will often find princesses involved in some form there as well.
Have a wonderful upcoming vacation!
