I lived in our sorority house for a year and it was a good experience. I was rough for me (only child) who had never had to share a room OR a bathroom to suddenly share a house with 40 girls, a room with 3 other girls and a bathroom with 20 of them. YIKES!!!
But, it did help me get to know my pledge class better, as well as the executive officers (they were required to live in the house).
My recommendation: If you move into the house, try to get a room that is a single or double. I wouldn't recommend sharing a room with more than one other person unless they are your very bestest friends!!!
