I usually end up just taking all my vacation at the end of the year in a big block. Part of the reason is we don't schedule anything very far in advance, so I am hesitant usually to use vacation days early in the year when I might want to use them later on. Also, my work schedule is flexible enough that there is rarely a reason to take time off. If I need to leave early, I leave early. If I need to go to an appointment, I go to an appointment. None of it affects my time off. And I guess maybe I just like routine?
