First I don't know if you are allowed to use your phones during the Expo events, but, for the people that want a live stream, why doesn't someone at the Expo just Facebook Live Stream the parks section from their phone? Everyone has the capability now and that way everyone can see it. I BELIEVE you can download the video afterward, and then upload the video on here, and people can watch it if they'd like. Whoever live streams it can have it shared by a page (if the DIS has a Facebook page that would be the way to go), then you just need to go on the DIS' Facebook page to watch it live.
