Christmas Week Question regarding entertainment at MK

So my DS is currently in DCP working at MK. We have planned to head down Christmas week (12/23-30) to spend some time with him over the holiday and get a look at WDW during Christmas which we have never done before.

I know the MVMCP ends on the 22nd, but I heard that in past years the parade from that party runs during the day at MK and the holiday fireworks happen all during that week.

Is this correct? Just wondering as we plan our park days.

Not sure if they are the same parade and fireworks, butduring Christmas week there is a Very Merry Christmas parade, instead of the normal 3 pm parade, and in the past there has been a Holiday version of Wishes. I am assuming that they will continue with a Christmas version of the fireworks, now that wishes has been replaced, but you never know.
