Th annual Winter Break emails from Barnard Residential Life and Columbia Housing are out, and it seems like the women of Barnard are getting something of a raw deal.
All Columbia students automatically have access to their rooms over break without even having to fill out a form. The only disadvantages, as described by CU Housing, are a limited schedule for custodial services and showers that warm up less quickly.
So other than some slightly colder showers and the potential that you might have to clean up for yourself for a change, staying in a CU dorm over break should be no more difficult than during the semester.
However, on the Barnard side, the situation is much less pleasant.
