Hi Rabia,
What a great question! Thanks for bringing it to the Disney Parks Moms Panel. While of course there is no right or wrong answer to your question, I will give it my best thoughts.
I suggest that you wear the Mickey Mouse shirt to Magic Kingdom, as Mickey Mouse is simply classic Disney, and
Magic Kingdom was the first theme park at Walt Disney World. The Star Wars shirt will be perfect for
Disney's Hollywood Studios. Disney's Hollywood Studios is home to some great Star Wars attractions, including Star Tours and Star Wars Launch Bay - be sure to check them out!
The next two shirts were a little trickier, but I think I have it figured out. I suggest your Mickey Mouse, Goofy and Donald Duck shirt for
Disney's Animal Kingdom. Finally, wear the Lightening McQueen shirt to
Epcot, and you can wear it while you experience Test Track, in which you design a car and then take a spin on an amazing track.
Thanks for submitting this fun question, Rabia. Have a wonderful time planning your Walt Disney World vacation, and please do let us know if you have any further questions.
