I was wondering the same thing. There isn't one on the schedule but I certainly wouldn't be sitting 7 hours for a parade. I've been checking in since about 1:30 and they've been sitting there the whole time. Maybe they'll do a Soundsational at 3? I haven't heard any park announcements though, maybe they are sitting there that long.
Thank you for the link! I'm going to bed now and am going to get up at silly o'clock to watch the parade! (I'm in the UK, in case anyone was thinking I had strange sleep patterns!)
