Unlimited vacation works well for me. Instead of hoarding my precious vacation days, carefully judging whether some occasion is special enough to justify rationing them out (therefore possibly having to miss out on something else, later in the year), I just... take time off, whenever there's reason to, and don't worry about it. I don't know whether I take more or less time off, and that's the beauty of it: I get what I want and I don't have to think about it.
