Vanna,
Things that we have done at Iota Sigma have included: (we don't have a house...)
-Sisterhood Joe Millionaire night
-Dinner at a local restaurant
-Nacho nite at Sully's (local restaurant)
-Ice Cream social in the dorm lobby during dinner
-Fie-ZTA
Those are just some ideas that we did this semester. I have seen some sororities do things like:
-Bowling
-Ice/Roller Skating
-Dressy Dessert
-Progressive Dinners (works if you don't have a house, or if you do, move from sister's houses and end at the chapter house)
-Karoake
I hope these help you a little bit. Let us know how everything turns out!!!!
ZLAM,
Meredith
