HI Shani,
Thanks so much for stopping by the Moms Panel. As a mom of a little princess myself, I can just imagine how excited you are about bring your twin girls to The Happiest Place On Earth.
Since your girls love Disney Princesses, I suggest immersing them in as much of the princess magic as possible. Magic Kingdom Park is the park of princesses, so I suggest spending 2 of your days there. A visit to Enchanted Tales With Belle will be an unforgettable experience for your girls. Belle interacts with the Guests, while reading a lovely story. It's a must-see whenever we visit. Seven Dwarfs Mine Train, Princess Fairy Tale Hall, and Under the Sea - Journey of The Little Mermaid are all amazing experiences that are centered around Disney Princesses.
Looking for dining experiences that your girls will love?
Cinderella's Royal Table is a must. Your princesses will enjoy meeting Cinderella, and having a wonderful meal within her castle. Not only will your girls have a magical time, but you will too!
I hope these suggestions help you with your vacation planning, Shani. If you have any other questions, please feel free to ask us anytime.
Have a fantastical Disney day!
