Hi there, Elizabeth! Welcome to planDisney and thanks for stopping by with such a great question.
It sounds like you are celebrating something special, Elizabeth, and I can't imagine a better place to have a magical celebration than the Most Magical Place on Earth. You'll be embarking on this pixie-dusted adventure before you know it, so let's get this planning party started!
Unfortunately,
Walt Disney World does not offer a service to have your room decorated, and for safety reasons, the Resort cannot give a third-party vendor access to your room. But Hakuna Matata! It means "no worries." Most of the Walt Disney World Resorts allow you to decorate your window, as long as you don't use anything that will stick around when you take it down. Vinyl window clings and suction cups with hooks are easy and safe ways to add some extra pixie dust to your room.
Another way to add some extra magic to your magical home away from home is with
In-Room Floral & Gifts. This is a service that allows you to order balloons, flowers, gift baskets of Disney goodies, and even adorable celebration banners online to be delivered right to your Resort. Some friends of my family had some of these goodies delivered to our room on one of our first Walt Disney World vacations, and the surprise and excitement I felt when I saw the balloons and gifts in our room after a long day in the parks is something I will never forget.
While this probably wasn't the answer you were hoping for, Elizabeth, I hope it was at least helpful! Please feel free to stop by any time with any questions you may have along the way.
Have the most magical time,
Mandy
