Definitely consider things you,ll need for table setting, including wine, water glasses, mugs or cups. Cups better for bulk as less filling, can refill, but extra washing in saucers.
Def put veg, spuds, gravy in jugs (ordinary are fine if you don,t have gravy boats), and other side things out not able to serve yourselves. I'd serve the meat on plates, but put extra on a serving plate for table either immediately or when people are going for seconds.
For starter, either a big pot of soup or something cold you can have plated up in advance that morning (smoked salmon is nice - buy pre sliced for ease).
Veg prep on Xmas Eve, put those needing it into water in pots, other in airtight tubs (Brussels sprouts or cauliflower). Make your stuffing too, and perhaps cook ham as easy to reheat.
Think about quantities and oven space. While turkey rests you,d get roasted veg done but probably need spuds in for some time same as turkey. A seperate dish of stuffing could also cook while turkey rests. Maybe do 1-2 rosaries each. But big pot mashedpotato as well on stove. Steam sprouts, do a mixed veg stir fry, steam/boil cauliflower and put into oven under blanket cheese sauce for few mins while turkey out. Gravy is stove top, could make day before to reheat just adding turkey juices.
Overnight guests. Beds and towels, breakfasts and late night cups of tea, chocolate and a snack.
Will they stay long, and mostly before or after Christmas? So do you need lots of easy prep meals in advance, or have plans to use leftovers in sambos, curries or whatever? Shops will open again after, but if staying long visit, you might want to have a decent meal planned for 27/28th that you order ahead, like a leg of lamb or beef joint, or a family favourite.
Have you a few things to entertain? Even options is good so bad weather or nice weather can be dealt with, or just boredom of some. Board games, a big jigsaw, "parlour games", tv schedule or a couple of box sets or sign up to Netflix or love film for a couple of weeks.
And definitely give people specific jobs in advance and when there. So you can enjoy too. A man might find cleaning and setting the fire ok, a woman very happy to wash up or make gravy.
And start to put things away now. Soft drinks, alcohol, boxes or mixed packs of biscuits, crackers for cheese, nice marmalade for brekkie, part baked bread rolls, packs of ready made custard. Paper napkins, tin foil roasting platters, tin foil and cling film to store things, kitchen towel, plenty loo roll.
And maybe put together the fruit now for hm mince meat, buy jus rol or similar pastry ready,are (and rolled if want for time) and throw together h&m mince pies in minutes.
Think of your strengths and play to those. But make sure you make time for yourselves too during the festivities to relax, and enjoy your DCs as well.
