What is something fun for a group of christian teenagers to do for a whole week

Question

I'm in charge of our youth group at our Church, teen week is coming up and we'll have about 30 teenagers to plan for. Any ideas at all? Camping is out of the question, we'd like something a little more civilized lol.

Answer 1

What eleemosynary institutions do you have in your area that could use volunteer workers where they could be productive?  

Answer 2

Bowling, laser tag, uh... try group-activity sports like soccer or baseball.
