Hi Alexandria, and welcome to planDisney!
Oh, dear. I'm so sorry your pretty parasol needs repair. It sounds like it's given you lots of joy over the years! If only Cinderella's mice friends were here to lend us a paw, I'm sure they could fix it right up for you.
I'm not aware of any merchandise repair services in the theme parks. I think your best option is to get in touch with Merchandise Guest Services with the contact information you'll find
here on the shopDisney website. They're the ones who can best help you figure out how to make your parasol right as rain again.
Alexandria, in case it's time to pick up a brand new parasol, you can still find them at the
Magic Kingdom Park! The Liberty Square Parasol Cart is located just across the bridge leading from the Cinderella Castle hub area to Liberty Square, near
Sleepy Hollow Refreshments. The parasol display looks like a bouquet of giant blooming flowers, so you can't miss it! You can get a customized work of art here that you'll treasure for another 20 years or more.
I hope I was able to help you, Alexandria. Enjoy your sunny day at Walt Disney World, and please come see us again if you have any more questions!
Keep Disney Dreaming,
Kathy K.
