I have seen a few, mostly around the holidays if they are doing CP. The most high profile, spontaneous sighting was way back. My sister and I were sitting on a bench right behind the castle, facing the carousel, and no one was around. A VIP guide came through the castle with a man, woman, and a baby in a stroller. Seeing them from the back, we didn’t know who they were. They stopped to talk and turned around, and it was Billy Joel, Christy Brinkley and their daughter Alexa in the stroller. The group stood and talked for a few minutes and then went into what was then Tinkerbell’s Toy Shop. The whole time this was happening, there weren’t any other guests in the vicinity.
