I have DCs, we do presents, decorations, Christmas Dinner etc, but it is quite pain free. Extended family are doing their own things this year, whether we are seeing them or not, we have a good time.
I enjoy the school performances etc, it's genuine and lovely to see my DCs doing something done for generations.
I have a box of decorations mustered up over 15 or so years. I enjoy pulling them out like old friends. I'm putting them up gradually.
Christmas dinner is just a roast dinner with a few extra trimmings. Admittedly, I'm not catering en-masse, but I can't get into a tizz over it, even though I rarely do roasts.
Buying presents is streamlined down to mainly children. I'm not working myself up over budgets etc, just something that I think people will like. My own DCs are complicated slightly by simulataneously sorting DS's birthday which is a bit extra to think of, particularly in keeping a fair spread of birthday, DS1, DS2.
I don't get hung up on "traditions". Each year we play by ear. Just because we did it last year, we aren't obliged to do it on repeat ad infinatum.
Plan the Christmas you are content with, whether it's minimal, the works or something in between.
(I accept that other people in the equations may have other, more complicating ideas...)
