We host Christmas day. Its me, DH, x3DC, my parents & inlaws.
We have dinner then sit around chatting all eve with drinks. By the time its the evening I sit looking at the mess of the house and thinking how much work it will be to tidy up, having already loaded/unloaded the dishwasher several times during the day and laid/cleared the table, kept drinks topped up, snacks replenished, manually washed up as we have ran out of glasses & plates & cutlery etc between courses and throughout the day. Dh cooks the whole meal (his choice and contribution) but he makes so much mess. Boxing day morning I then spend clearing up the second half of Christmas day which includes a full floor wash, more loading/unloading the dishwasher, full tidy up, trying to fit the food leftovers into the fridge, kitchen wipe down and clean. Its exhausting.
I wouldn't ask the parents to help, they have spent their life catering for us/doing Christmas over the years Its their time to relax.
Going out for dinner is not an option.
