Volunteer, get a free-trial to a gym at home for one to two weeks, visit your old grade school or high school on a day when they are back in school, clean out old clothes and see what you can donate to charity, road trip, go antiquing or to wineries, after Christmas shopping, go to museums or the zoo or whatever you can find that is free, rent movies, go out with friends.
Hope that helps.
I miss winter breaks; working in the real world is no fun!
