Our MK afternoon parade ritual is this.. stake out our spot along Main Street near Casey's Corner ( hot dog stand) at about 2 ( or an hour before the parade starts). My DH usually sits with 2 kids while I take one to help me carry things. We sit along the curb in our great spots while we have our lunch. So we get much accomplished.. get a good seat, take an hour + break, and eat lunch. The ice cream stand is right there too, so the kids usually get ice cream too.
We like to watch Spectomagic in Frontierland! It doesnt get crowded as fast as Main Street. ( Not in January anyway) We sit near Liberty Tree Tavern by the ropes.
In Animal Kingdom, we sit near Pizzafari to watch Mickey's Jammin Jungle Parade. Then when its over, we zip down to watch Lion King.
MGM.. we like to sit near the ABC studio thing ( with the steps). We snagged some benches near the steps and had a great spot in January! The kids ran around by the statues and had ice cream while we waited.
