American here. I would use 204: 250 - 10 holidays - 10 days of summer hours (something my company does in the summer) - 26 vacation days. My vacation days can actually rollover from year to year (up to a maximum of 60 days), so I could take off more vacations days. But, at a minimum I will get 26 days of vacation (on top of the 20 days of holidays and summer days) per year.
