Sounds great. Have an awesome time and keep your mind open. You'll find the perfect place for you.
About being in groups of four in individual girls' rooms. I'm not trying to stir things up, but at my school that would be dirty rushing. Hotboxing is what I think it's called, I'm not sure though, I do know that it is against the rules. All the rushees are supposed to be in the same common area of the house. It could be just at my school.
Please don't let my question make you think poorly of the girls, I was just curious.
