Does your holiday time accrue so that when you hit a certain amount, you can cash it in?
When I was in the Army, we got 30 days paid vacation per year, and you could accrue up to 60 days before you lose it. But you could cash it in (for a month's pay) or just take a vacation. A few times, I did both. Save up 60 days, cash in 30, then take 30 days off. I found that I don't like more than a two-week vacation, so I planned better around that.
