My parents are checking me into a alcohol rehab center. What should I expect?

I do know that Im gonna have to live there for a long time and I know about the phases and privledge points and blah blah. I mean what will I have to do? Will they just make me sit there in a room or what? Theyve gotta make us do something. Im 14 if it matters.
