Call me strange, but I actually feel pretty confident that Paint the Night will show up at MK in the near future. No, not October 2021 unless COVID levels really go away quickly, but heat me out....
At some point, we will return to more or less "normal" and the parks will be run as they were before in terms of entertainment. And Disney will want to do something to "celebrate" the 50th (even if delayed) and can wrap that into having a sort of grand re-opening of normal levels. And if they want to do something splashy, adding a "new" light parade certainly fits but they also realize they can be totally forgiven for "going cheap" and reusing due to the current economic situation. When it comes to advertising, a light parade plays real when on TV, print, whatever.
My thoughts are if they can allow gatherings for HEA, limited or not, they should be able to do a parade. And they will be doing a parade and fireworks, I’d assume, if they allow MNSSHP to return. Guess we’ll see.
