1 house at pref night

So did very many PNMs only have one house today at pref night? I had 3 but really am only interested in 1. So I was wondering how many already know they are in that house since it was their only party today. Maybe their pledge class is already full. I feel like having 3 should have been good but somehow I feel like having just 1 would have been better. At least I would've already known. It seems cruel that some know and some don't. I hope that isn't too many girls.
