@taanegl whatever you do, don't stay at home. This is a great opportunity to travel places. I spent my previous two Christmases alone in my house and I felt miserable. Try going to some place where you could go in the morning or return to the evening if you don't afford/cannot get accommodation. Or, if you can, book a ticket in a sleeper train in one day in the evening, and another in a sleeper train back in the evening of the next day (that way, you could combine the cost of the accomodation with that of the transport, and you could come out cheaper and save time). Try getting through all the best parts of that place - maybe check for information about that city on Wikipedia or anywhere and take some photos (it could also be an opportunity to get into photography if you want. That'll help you out as well. Then start categorizing your pics into a photo management program, you'll keep yourself busy a lot).
As for me, I think I have enough chores to do to keep myself busy. Plus some movies to watch and a book to finish.
