Sorority Pledges Living in the House?

[KillarneyRose]

Hey all! KillarneyRose de-lurking here with my most recent question about sorority rush...

Whenever sorority life is portrayed in books, movies, tv shows, etc., the girls always move out of their dorms into the sorority house once they become pledges. Does it really work that way? Are the dorm housing contracts written so that they can be broken if the girl accepts a bid?

The sororities at my alma mater have suites that can accommodate 20 girls or so, so there's no question of pledges moving in.

Second part of the question: if pledges really DO move into the house, what are the accommodations generally like? Sleeping porches?

Thanks ladies!
