Olympic champion and swimming star Michael Phelps visited the Magic Kingdom at Walt Disney World today. He rode down a balloon-adorned Main Street USA in grand fashion, with guests waving American flags as red, white, and blue confetti flew into the skies.
We’ll have a video of the complete procession down Main Street and a brief interview with Phelps online later today. In the meantime, be sure to visit our photo gallery for some pictures from today’s special event.
