my dorm is set up in suites. There are 3 floors and each floor is divided in half. On my floor theres guys on one half girls on the other. Theres a common kitchen area, 7 rooms(1 RA, 3 doubles, a triple and 2 singles. We all share 2 showers and 2 toilets.
My dorm is set up like this (transfer student dorms, off campus. It rules)
Two stories, four rooms per story. One person per room. Two rooms share one bathroom (seperate doors to the bathroom) and four rooms share a central kitchen. You can get in and out through an outside door. Its awsome.
