The years we stay at home are close to perfect (we have to travel some years - and eat 2 turkey dinners and fail every time try and keep the 2 DMs happy racing between the 2 houses we grew up in).
We do most of the main prep for proper roast on 24th, as a family - so it's mostly a case of putting things into and taking them out of the oven - a very small amount of "zhushing" (is that the word?) like putting the already herbed butter onto the root veg after a short steam before going into the oven.
At home, DD is generally not dreadful for early starts - usually between 7 and 8, so she opens her stocking and we all have a relaxed breakfast in pjs, of fresh OJ, large pots of tea and coffee, freshly baked pastries (either Jus-Rol from fridge, or M&S from freezer), bacon sarnies, bowl of mixed fresh fruit etc.
All into decent clothes (no sports leggings allowed for DD - must be jeans, but we've given up on dresses/skirts or anything fancy) - I usually wear a dress, DH at least a shirt and tie level of formality.
Out for mass, a walk to waste some time after it, and a couple of visits to extended family living near us.
Home - turn on tree lights, turn on radio/spotify, light fire, turn on oven, final prep of turkey and throw it in, throw in some M&S party food, open wine and nice drinks, leave kitchen tidy...
Enjoy opening presents and relaxing for a couple of hours - intermittent forays to kitchen to put something else into the oven or baste turkey or take something out as needed, when refilling glasses (and bowls of crisps) as necessary.
Enjoy a nice dinner.
All clear up together.
Relax watching some seasonal tv, or a movie, or playing a board game.
Maybe have some cheese and crackers, and/or proper pudding, later when turkey has digested a bit, possibly with a glass of port.
