Thank you for your question to the Disney Parks Moms Panel Ella! I'm so thrilled for your princesses' first magical visit to the Walt Disney World Resort this Spring.
We absolutely loved Disney's Frozen as well. I love that they pretend to be just like Elsa and Anna. I can just imagine them singing the, "Do you want to build a snowman?" song.
Your family will have the opportunity for a Meet 'N' Greet with Anna and Elsa from "Frozen" in the Norway Pavilion in Epcot and also in Fantasyland in Magic Kingdom.
Be sure to stop by Guest Services to get your free celebration button for their first visit and have the girls wear them throughout their vacation. Cast Members that see the buttons will send your family warm wishes throughout the day.
I hope this helps and that you have a wonderful time. Please write us back if you have any more questions planning your Disney vacation.
Wishing you a pixie-dusted day!
