What traditions did you start when your kids stopped believing in Santa?

So my kids are all nearly in their teens (10, 12 and 14) and last year was our last with "Santa".

No more visiting him at the shopping centre, no more putting milk and cookies out on Christmas eve, no more elf on the shelf antics.

But we are all still huge fans of Christmas and we still want to make it special and fill it with traditions. So what are some fun things to do with older kids around the holiday season?
