We've been there twice during filming. Both times it was the 2nd Saturday of December. I'd guess that it's weather-dependent. We were unaware of any general announcement within the resort and just happened to discover that it was taping day when we got to MK. The first time I wanted to tape the parade from the curb. Since a person with a camcorder stuck to her face doesn't make for good TV, we sat just off camera in the circle outside of Tony's. If you've ever watched on TV, the people on Main Street are standing. There are some breaks in the progress of the parade while the taping occurs to get special acts lined up, camera angles, etc. That's a lot of standing. Because the Santa finale includes special dancers, etc for TV taping, there's a big break as Santa hits the bottom of Main Street. Being part of the parade is fun, though it can be tiring and take longer than you expect.
