Hello, Laura!
My family and I typically spend at least one full day at Magic Kingdom Park on each of our Walt Disney World vacations, and after many visits, we still haven't experienced everything this magical theme park has to offer! I think your preschoolers could enjoy spending two full days exploring Magic Kingdom Park on your vacation because it offers the largest variety of attractions and character greetings that appeal to their ages. There are even some more thrilling attractions that your daughter could enjoy with a parent, like Seven Dwarfs Mine Train.
Epcot is my favorite park at the Walt Disney World Resort, and is a wonderful experience for children of all ages. My daughter especially enjoys walking around the World Showcase area of the park, sampling new foods and learning about other cultures along the way. Each of the countries represented in World Showcase offer plenty of educational value, and your children can take part in free children's activities at each of the
Kidcot Fun Stops as you travel the world. Make sure to have an autograph book ready for any special Disney Princess friends you come across -- many of the princesses like to visit with guests in their own native 'lands' at World Showcase!
If you are looking to add even more variety to your three-day trip, you may want to consider Disney's Animal Kingdom Theme Park. Your family can take a walk on the wild side and visit with many exotic animals from around the world. Your children could also work as a team to earn badges with the free
Wilderness Explorers activity. There are over 30 badges to collect!
I hope you and your family have a magical Walt Disney World vacation, Laura. Please stop back by the Moms Panel if you have any additional questions. Hope to see ya real soon!
