Hi Athanasia!
Thank you for bringing me this fun question! My daughters are the exact same ages as yours, and I have to tell you that these are the absolute best ages for a first trip to Walt Disney World Resort! You will have a magical time!
Here are my top three recommendations for your family! First, be sure to schedule one meal with Disney Princesses. My family loves
Akershus Royal Banquet Hall in Epcot and Cinderella's Royal Table in Magic Kingdom Park. Second, be sure to enjoy some down time at your Walt Disney World Resort hotel. There are many activities at the pool during the day and evening fun includes
campfires and outdoor movies under the stars. Other family-friendly activities could include renting a
Surrey Bike and going for a spin! My family rented a Surrey Bike at Disney's BoardWalk this summer and we had a blast! Third, your daughters might enjoy my girls' favorite attractions: Seven Dwarfs Mine Train (Magic Kingdom Park), Test Track (Epcot), Expedition Everest - Legend of the Forbidden Mountain (Disney's Animal Kingdom Theme Park) and Toy Story Mania! (Disney's Hollywood Studios).
Yes, we love
Disney Phineas and Ferb: Agent P's World Showcase Adventure in Epcot - I highly recommend it!
Sorcerer's of the Magic Kingdom is also very engaging; your girls will enjoy it!
I hope this helps answer your question, Athanasia! If there's anything else I can answer, please let me know; I'd love to help! Have a magical day!
Erin
