Hello, Amanda,
Thank you for sending your question to planDisney. I think this is such a precious memory you and your sister have of visiting the Magic Kingdom. Your mom created some magical pixie dust in making those experiences for you both, and it is even more wonderful that you are both trying to pass along that tradition to the next generations.
I checked the menus at the Magic Kingdom, but I was unable to find any Key Lime Pie. However, I do have an idea that may work to carry on your mom's tradition. The
Grand Floridian Cafe is a restaurant at
Disney's Grand Floridian Resort & Spa, and it has a Café Key Lime Tart on both the lunch and dinner menu. The resort is right across from the Magic Kingdom with easy access by monorail, water taxi, or even walking. You could enjoy lunch or dinner at the restaurant (I suggest making
reservations beforehand), and then get the Café Key Lime Tart to go to bring with you to the Magic Kingdom to carry on the tradition your mom started. If it looks like it might be hot, you can store the dessert in a cooler (it cannot be bigger than 24" long x 15" wide x 18" high) with ice packs (no loose ice or dry ice allowed).
To help make the memory even more special, Walt Disney World offers a
Capture Your Moment. It is a 20 minutes photo session to capture the special moment for your family. It is highly recommended that you make
advance online reservations.
Wishing your sister and her family a magical trip! Please let us know if you have any further questions.
