I don't think you will see a MVMCP this year, but probably something similar to what they are doing with the Halloween event.
However, its months away, so it could be more.
I would think we would have some details 3 months before it starts to that would be August. By then there may be a big ease on restrictions and a more normal party event as opposed to the Halloween event.
I don't usually care a lot about parades, but I I love the Christmas Parade at the party. Not sure I would want to go to a Christmas Party (or whatever they might call it,) without the parade.
