Just speculating here, Assuming all age groups opens by July, at least I think that was once the idea, hopefully sooner, maybe the CDC which Disney is following to the book it seems, will see what things look like in 2 or 3 months allowing the majority to get a chance to get the vaccine, Then they might support relaxed social distancing or no social distancing by November ish. IF things continue to go in a positive direction and no hiccups. Maybe that’s one of Disney’s scenarios.
Should it play out that way, the bad news is we will have wait until the Holidays to see nighttime shows, and this would likely kill MNSSHP this year or have a watered down version... But the good news is MVMCP might be saved and with fireworks, along with HEA on non party nights, Harmonious and Fant.
