You have some magnificent decorations. Making nutcrackers sounds like awesome fun!
Personally, I'm not sure that there is any one part of Christmas that I like more than any other, though I'll admit I do miss a snow-covered December. I enjoy going out and being in Christmas markets. I might be one of the few people that enjoy being in shopping malls this time of year; there is something satisfying about carrying around bags of goods that you know people will enjoy. It is also incredibly satisfying to be able to find One Last Free Table in the food court to sit at with a snack.
And Christmas beer! A heavy stout laced with cinnamon in the front room with the Christmas lights for company. Advent calendars. Strangers actually smiling. And I still feel like a child again every Christmas morning, and don't complain (too much) when the kids wake me well before the sun. That's also the one morning of the year they're willing to make me coffee.
