It’s an event five decades in the making! Beginning Oct. 1, Walt Disney World Resort will throw “The World’s Most Magical Celebration” in honor of our 50th anniversary, bringing new experiences to our four theme parks and beyond. This milestone is such a big deal, we’ve even coined a new word – “EARidescence” – to describe what you’ll see when you visit. Our Disney teams are creating all sorts of new decorations that will shimmer and sparkle all day and into the night.

The castle will add even more magic at night, joined by icons at each of the other three theme parks as they transform into Beacons of Magic. In the video above, you can get a feel for what they’ll look like, with pixie dust on Cinderella Castle, magical fireflies inhabiting the Tree of Life at Disney’s Animal Kingdom Theme Park, and special new touches coming to life on the Hollywood Tower Hotel at Disney’s Hollywood Studios.

And at EPCOT, new lights will shine across the reflective panels of Spaceship Earth, connecting to one another and resembling stars in a nighttime sky. This permanent new lighting will continue beyond “The World’s Most Magical Celebration” as a defining feature of the park.

You’ll also want to keep an eye out for Mickey Mouse and Minnie Mouse, who will have sparkling new looks for the celebration. As hosts of the event, they’ll be dressed for the occasion in custom-made fashions of EARidescent fabric with gold highlights.

In anticipation of this exciting time, we recently went out across Walt Disney World to talk with guests and Disney cast members about what a magical celebration would mean to them and why they love being here so much. This new video captures a lot of the emotions we’re feeling right now as we prepare for our 50th anniversary:
