We were there for the taping in December 2006. What a ZOO! You could go to some site, I don't remember what it was, and get passes to be apart of the taping, as extras, for the parade(got you in the front) and the performers. However, you could be a part of the parade with out the passes, you were just in the back with the commoners, unless you found a way to squeeze in. You could also see some of the performances. It was done the first weekend in December, and the performers were filmed on that Thurs. and Fri. from 7 or 8 am until 11 or 12, if I remember the hours right. Of course you couldn't see the performers that started before the park opened unless you had the pass.(All the good ones were early) We did catch the end of the HSM cast, kind of. Like I said it was a ZOO. Thurs. and Friday's taping weren't that bad, but Saturday's

The back side of MK(away from Main St.) was great until about 1pm or so. Then they stopped taping, and released the masses. That park filled up worse then 4th of July I swear. We had to leave, I couldn't stand it. Finished the day at EPCOT.
If you don't mind the crowds, and have nothing else to do or really just want to be a part of it, go ahead and try it. BUT, it really isn't that great. If anything I would try to watch for when the passes are being given for the performances, forget the parade. It's pretty much the same as the
MVMCP anyway.
Ok, went back and found the site that gave the info on the taping passes, etc. It's the production company's site. Here ya go...
