Actually you can take an entire week off and you will still get paid for that week that you took off. I would say you can take off a week max, at least in the Silicon Valley area. There is a 1700hr requirement that you have to complete by the end of your service date. As long as you are on track or ahead of your hours you can take as many days off sporadically as needed.
As an Americorps member, you have no paid vacation, only the days the school has off or if you keep ahead of required hours.
