For a Disney Theme Park Souvenir: Create Custom Mickey Ears at Le Chapeau in the Magic Kingdom. Here’s a great tip on Disney Theme Park Souvenir from one of my readers…
Many people when they go to Disney want to get the souvenir Mickey ears. We found that getting them at Le Chapeau on Main Street in Magic Kingdom allowed the kids to customize their ears, including embroidery of their names, for about the same price as a regular pair of ears. They get to choose between various base hats, different ears in a variety of designs and the color, patches and font they would like for their names.
Plus after you make these, you can bring these and other Disney souvenirs back to the parks on your next trip.
