With SAP, you can make your vacation last 2+ weeks. Even if the trip before a vacation doesn't touch the vacation, we can drop it. Same with a trip after the vacation.
With a vacation, you should be able to get at least 15 days off in a row. If you play your cards right, you can get 18+ days off with a single week of vacation.
Think about this... SAP the first 5 days and the last 5 days of every month off when you don't have a vacation. That will give you 10 days off in a row every month.
