Hi Kerry,
Your vacation with your two princesses is SO soon! I bet they're squealing with delight and counting down the days!
I have little girls as well and my first thought is that you'll definitely want a full day at Magic Kingdom Park. Your girls will step right into the magic and love seeing some of their favorite stories come to life. Plus, they'll be able to meet some of the
Characters who inspire them to believe in their dreams. Beyond your full day at Magic Kingdom Park, I'd probably ask yourself what kinds of things your girls love most. For example, if they are
animal lovers and enjoy thrilling attractions, I'd encourage you to spend your second full day at Animal Kingdom Park. If they love crafts along with attractions and want to know what it's like to travel the world, they'd love all of the
Kidcot Fun Stops at Epcot and would enjoy a full day there. If they love experiencing live entertainment and watching their favorite movies come to life, Disney's Hollywood Studios is right up their alley.
My general feeling, though, is that one day at Epcot and one day between Animal Kingdom Park and Disney's Hollywood Studios might be best. Now with that said, if you can schedule your day with two theme parks early in your vacation, that would ideal. That way, if you find that there is more your family would like to experience at one of those two theme parks, you could always hop back over there later in your vacation on your Epcot day.
I hope that helps you plan a bit, Kerry. Please let us know if you have any other questions, and have a truly magical vacation with your girls!
