Since there is no parade following us you do not have to get there very early. Parents who have done this in the past have gone an hour to an hour and a half prior to get a good spot to see the band. With no parade there is really no need to be there more than 15 minutes prior to Parade time.
For Wednesday's parade we are marching at 10 AM coming out next to the firehouse just inside the front entrance of the Magic Kingdom. We are then marching down towards the castle, around the circle in front of the castle and out through frontierland. The best places to watch the parade from are on top of the train station by the main entrance. You'll be able to watch the band go around the circle there. Another great place where out parents will be meeting will be in front of the castle by the circle. The kids will then get released out of a door next to the Pirates of the Caribbean after they change into their street clothes..
We are scheduled to play at 10 o'clock which means we would probably be coming out at the beginning at 10 AM if there is not another band before us. I will try to tweet our progress from backstage if I can.
