We have separate holiday meals for our 4 daughters and their larger families. Typically Advent Sunday soon after Church. They each choose their own menu, we cook in advance that which is possible, clean up after they leave rather than wasting time in the moment. Pressies, then on their way to their homes. Easy.
For us we have Christmas together after Church, around 1 in the afternoon, off to walk dogs by 2 or so. I like things fast, easy, and done.
They all pop round, in and out, whenever they fancy before and after Christmas - but not at their sisters' (or our) set Christmas Lunch times.
