Every year we go out into the woods and pick our tree and cut it down ourselves. Then we drag it back to the car and when we decorate our tree at home we have a box of Ganong chocolate and have X-mas music playing in the background.
As for Christmas Eve we always have Christmas dinner with my in-laws and we open our presents there at midnight.
On Christmas morning when the kids wake up they can open their Christmas stockings but nothing else, while I cook a huge breakfast. Once we are done then we each open a present in turn until all the presents are open.
I have also done a few scavenger hunts, where they find something big. As in one year I had them go around the whole house until they found a dvd to announce that we are going to Disney World.
