Hi Alexis,
Welcome to the Disney Parks Moms Panel! What perfect ages your children are for their first visit to the Walt Disney World Resort! I can imagine their wonder and excitement when they meet Mickey and Minnie Mouse!
If you are staying for seven days, I would suggest getting at least five-day theme park tickets. Doing so will allow you to visit at least one park more than once. We typically visit Magic Kingdom more than once during our visits.
There are many must-do experiences! Be sure to make
Dining Reservations for
Character Meals. Some of our favorites are Chef Mickey's, Crystal Palace, 1900 Park Fare, and Hollywood & Vine. My girls dance with Mickey and Minnie at Chef Mickey's and love hugging Winnie the Pooh at the Crystal Palace. By far, one of our most special experiences has been to dine in the castle at Cinderella's Royal Table.
Book your
Fast Pass+ reservations. We have used Fast Passes for the Seven Dwarfs Mine Train, Princess Fairytale Hall, Toy Story Mania! and Test Track. Remember to check out the
Frozen Attractions as well!
Also consider Jedi Training - Trials of the Temple. Sign-up only occurs on the day of your visit. You must get to Disney's Hollywood Studios, enter as soon as the park opens and head directly to sign-up at the Indiana Jones Adventure Outpost.
Last, the
Bibbidi Bobbidi Boutique would be a special experience for your little ones.
I hope this helps!
