This is the facebook page for WSU's panhellenic and pictures of recruitment. To be honest, I don't see many (if any) tank tops among the pictures, although I have no doubt there were some. Of course I have no idea how old those pictures may be. They look pretty recent.
This is the recruitment website page:

They also give last year's schedule here. Orientation is on Monday/Open house is split over Tuesday and Wednesday/Philanthropy is Thursday/Friday is House tours/Saturday is preference and Sunday is Bid Day. They apparently flipped Philanthropy and house tours from when daughter went through. I know she did house tours first - the schedule is very specific.
I would think long and hard before not listing ALL of the chapters you still have on your preference card. If you just think there is NO way you could ever possibly happy in that house and you would rather not be Greek that go into it, then don't list it, but be aware that usually not that many houses do informal recruitment (four the year she went through and I think less last year) and one of those houses could likely end up being the house you didn't want at preference.
