Christmas themed dinner party suggestions

[hairycabbage]

Instead of going out we are having a night in with five other couples and looking for ways to make it a bit more interesting/ special/ Christmassy.
Doesn't have to be a sit down meal -buffet is fine and we can ask everyone to bring a donation for it.
So far I've thought of asking everyone to bring a Christmas themed cocktail/ mocktail/, secret Santa, Christmas quiz, fancy dress...
Anyone got any suggestions for ideas to make it memorable? Not all of them drink so anything strongly alcohol related is out and there's also one single person so Mr and Mrs type games don't really work either! We do like 'themed' nights such as Murder Mystery, fancy dress etc so anything would be considered!
TIA

We’ve done ugly Christmas jumper theme with a prize for the ugliest jumper.
Elf theme
Reindeer theme - everyone wears antlers and a red nose! Play ‘pin the nose on Rudolph’. Serve this M and S dessert christmasfood.marksandspencer.com/rodney-cheesecake-serves-10-/p/p60434633
Christmas around the world
Scandinavian Christmas (lots of fair isle and rustic decorations)
Nightmare Before Christmas - make use of all those leftover decorations from Halloween.
Winter Wonderland - decorate your party space to look like a wintery palace, with white draping, fairy lights, ice sculptures, snowflakes, and polar bears. Serve this white chocolate snow dome from Sainsbury’s food-to-order.sainsburys.co.uk/product/7989285/ttd-belgian-white-chocolate-raspberry-snow-dome and/or this igloo ice cream dessert groceries.asda.com/product/ice-cream-party-desserts/asda-igloo-iced-cream/1000093637478

This is a lovely Icelandic tradition...

Book present and hot chocolate on Christmas Eve. You could do that?

Don't forget crackers. And indoor sparklers.

Love these suggestions! Thanks
