I love Tracy's answer & will add a few of my own:
-Make a gingerbread house together
-Go out together & buy one new, neat ornament for each person in the house
-Adopt a family (giving them a Christmas visit on Christmas Eve or the
day before and you buy them small gifts. It is for less fortunate families
-Make cookies together
-Go visit Santa & have a picture taken
-Go see a Christmas play in town
-Go see a Christmas movie together
-We have hot cocoa w/candy canes hanging from the ring of the mug,
whipped cream, red sprinkles & cookies (most nights) You can spike
the adult's mugs if you want ;)
-have a family party if your relatives live nearby (it can be small & just have them over for cocktails, appetizers & desserts for 2 hrs one night)
-Christmas mass if you are religious
-One year we made our own graham cracker cookie houses & decorated
w/frosting, edible decorations etc
-One year we went to see the Nutcracker etc
Have fun, enjoy & happy holidays! :)
