Hi Jamie!
So much fun! I really do miss certain ages with my kids, and your daughter's age is certainly one of my favorite times with my own little ones! The fun, the energy, the discovery, the priceless reactions...so amazing!
I'd definitely suggest
Magic Kingdom® Park for your little princess! My own are now 9, 7, and 4 and Fantasyland is still very much of of their favorite places in
all the parks to be! There are so many classic favorites there such as Dumbo the Flying Elephant®, "it's a small world"®, The Many Adventures of Winnie the Pooh, Peter Pan's Flight®, Prince Charming Regal Carrousel, Under the Sea ~ Journey of The Little Mermaid,(just to name a few!) I think y'all will have a fantastic time! You'll also be able to visit with Mickey Mouse as well as some of his close friends! Magic Kingdom® Park is certainly the place for the little ones!
Do make sure you stop by City Hall and get her "My First Visit" button to commemorate her first visit!
Have a magical vacation!
Amanda
