My DC are adults (they'll be 24 and 21 by Christmas)
Christmas now is much more low key and I do miss Christmas with young DC but I was much younger myself
I couldn't do it now !
It's been streamlined over the years so now :
Dec 1st Hamper rather than a Christmas Eve Hamper .
They get pyjamas/loungwear (winter not Christmas) so they can start wearing in Dec.
Socks/underwear (and any scraggy ones get recycled)
Bathrobe every 2 years
Showergel/face products
Sweets+selection box but no Advent Calendars this year
I used to do a Beauty Advent Calendar for DD and put each days gift in her room but it is trickier to find things . Last year I did a gift box with nail polish,lip balm, cuticle balm, hair scrunchies ,hand/foot masks, face mask.
This for Dec 1st too.
I like the cooking on Christmas Day , it's quite relaxing doing the prep , but I do need help with the table setting and getting it all set out and the dishes cleared .
Dinner was always After Dark and Before Dr Who . So we stuck to this 
No tree or candles (though I use LED ones) as the cats are vandals .
I always work between Christmas and New Year (NHS) otherwise its a shock to my system going back .
This year I;m going to book some A/L the week before to pace myself (and watch rubbish-ey films on Hallmark)
I've never fancied Christmas away or dinner in a resturant
