We were at the MAgic Kingdom the day they taped it last year. First, avoid the park that day unless you want to be in/see the parade live. If you do want to be in the parade scenes, you need to get there early and they will want you to stay all day, that seemed like a huge waste of our time, so we didn't do it. Main Street was a complete nightmare while this was going on, had I know that was the parade day we would have went to another park. Also the whole park was PACKED that day. So my advice is that if you don't want to be involved in it, steer clear and go to another park, I bet all the others will be pretty empty!
