Tips on cooking Christmas dinner for large group

Hi all and Merry Christmas.

Ok so I stupidly volunteered to cook Christmas dinner for 11 people (9 adults and 2 children) this year!

So was looking for tips/hacks on timings for getting everything cooked on time.

Initial ideas are;

Roast the Turkey for the time it takes to cook, then take it out and let it rest for up to 2 hours. Towards the end of cooking the turkey, stick in the stuffing and cook so it comes out at the same time as the turkey.

In the 2 hours resting time, roast the Carrots and Parsnips for 11 people (these are going to be par boiled bight before). Once they are out, stick in the roast potatoes (again par boiled). Towards the end of the potatoes roasting, start boiling the brussel sprouts. At this time I will warm up pre-made gravy and add turkey juices.

At the end of the potatoes cooking, stick the stuffing and other roast veg back in the oven to heat back up. Take the turkey out and carve, then serve everything warm.

Does this sound like the best way to do things? What is the maximum time you would let your Turkey rest?
