Hi CeCe - FSUZeta is correct about SEC schools, and living in the house is a privilege and a once in a lifetime opportunity; but it is also sometimes a responsibility for membership. I, like FSUZeta, was fortunate to live in the KD house at Arkansas for 3 years, and had an AMAZING time that in many ways molded me into the woman I am today. I believe that currently the KD house at Arkansas sleeps 71. If you get the opportunity take it!
I would check out the Greek Life website at each specific school you are interested (just google search them) and the answer might be there, and if the answer isn't on there, that is a GREAT question to ask the Greek Life office either in person on a campus visit or through a phone call.
Good luck with finding your college home and getting more information about Greek Life! And, if Arkansas isn't on your SEC list, give it a second look
