The parade is taped on Sat, misc. acts are taped starting on Friday, continuing into Sat. On Sat they get started very early with the parade taping...early morning. Then, the taping can last up to 5 hrs....a float will go by, then go back to it's starting point again, and they will run it again. It is very slow, tedious work. Since the afternoon parade starts at about 3, I would imagine they are done with the Christmas parade taping by then.
But, there will be a ton of folks in MK on that day...you add the extras for the parade taping, those who come in with hopes of being at the taping, in addition to the normal Sat crowd...yep, it gets a bit congested in there that day!!!
