No to guilty feelings!
We have too many (40+) for an indoor family meal, haven't had family Christmas lunch in many years. Our married daughters, with married children, and their grandchildren do what they need to do with their families for Christmas lunch. As it should be, I think. Apart from logistics, it's chaos.
We have a meal, their choice of meat/menu, with each of the 4 families, during the Advent run up to Christmas.
We have cookie bakes for days, Glühwein in the lights inflatable garden, go to various nativity, panto, and productions.
Similar to you, enough is enough. No all family meal.
