I don't know what is universal to share - but as a personal note I just want to say how very much I love my family. Everyone is gathering - everyone is happy to see each other. We're crowding into a 2-bedroom apartment, eschewing the opportunity to have some sleep across the street at a hotel, because no one wants to be separate. So out comes the air mattress and extra sheets for the couch!!
With togetherness our agenda, it matters little what we plan "to do". "Doing" is so very secondary to "being". The doing will include (of course) cooking and eating, waiting for the next to arrive, followed by some surprises in the stockings and one gift for/from each (drew names this year).
In wishing you a Merry Christmas, I don't choose to be politically correct in my language because the holiday is about love, by whatever construct one defines it. Setting aside time to be together creates a holiday of tremendous magnitude. Simply joyous.
