not sure about auburn, but the way i understand it is that the pnms are the only ones getting the break, and not everyone has a break at the same time, except the first round when they are going around in rush groups together.
They did that at my daughter's school last year, too. They just added one party to the first day because there were so many girls going through recruitment. They didn't know about it until a day or two before rush started, though.
