Hello, Henrick!
Thanks for stopping by the Disney Parks Moms Panel with your question. You will have 4 full park days, do I have that right? There are four major theme parks at the
Walt Disney World Resort. They are Disney's Hollywood Studios, Disney's Animal Kingdom, Epcot Theme Park and Magic Kingdom Park. Each park has something special to offer guests. In addition, each park easily appeals to children of all ages. Take a look at the link I provided you which will outline each park in detail. In my opinion, Magic Kingdom Park should be number one on your list. It is the most iconic of all four parks, and it's truly magical. With the recent addition of New Fantasyland, it's even better than ever.
As you begin to narrow things down in terms of your "must-do" parks, feel free to come back with any additional questions. We are always happy to help.
Until then, I wish you a truly magical vacation!
