Sigma Psi organized the last convention. I remember requesting the info packet from them and passing it on the sisters in my chapter (i was alum at the time). I didn't attend, but I was super impressed with the materials I received and how well-planned it looked. Because everything was help on-campus at Case-Western, the costs were really low. I would reccommend getting in touch with Sigma Psi to see if they could be of help to whoever wanted to plan this year's convention.
