17th Birthday Ideas?

I'm not really sure what to do for my 17th birthday. It's on the 15th of December so since Christmas is soon I don't want to do anything too big/expensive. The thing is that I've just moved, so my whole house is covered in boxes, I could make some space, but not to have many people over. Also, I've just changed schools so I don't really know if I should invite old friends, new ones, family friends (as in adults and their kids who are different ages to me) or all of them and what to do since they won't know each other.
