I think some of it may be staged--along the lines of how some of the real world is staged. I know MTV provides alcohol free to cast members to provoke things to happen--I wonder if this is what they do with Laguna. I read in another thread that the cast is completly made up (names, ect). One of my friends sent this link to me and it seems to be a girl who is from Laguna. Makes me uber jealous!
