Hi there Lesli,
I'm so glad you wrote us here at the Disney Parks Moms Panel with your question. I hope you are having a Silly Symphonies day.
Your family is going to have an enchanting time at the Walt Disney World Resort making memories that will last a lifetime.
Here's a spoonful of sugar to help this medicine go down; while you can't conduct your own ceremony independently in the Disney theme parks, you can visit
Disney's Fairy Tale Weddings & Honeymoons to book a magical wedding while at the Walt Disney World Resort. There are three different collections, the bride and groom may choose from, like the Memories Collection, with Hotel Resort locations like Disney's Polynesian Resort, Disney's Wilderness Lodge, and Grand Floridian Resort & Spa.
If your husband attempts to perform the ceremony, he and the wedding couple could be asked to leave the parks. I hope this helps in everyone's decision.
I hope that you have a wonderful time at The Most Magical Place on Earth. If you have any more questions, please visit us here and let us know how we can help you plan your magical vacation.
Have fun showing your Disney Side!
~ Lynette
