At the University of Michigan-Flint you are not "forced" to attend all the preference parties that you are invited to. We only had three sororities so basically all of the Rushee's went to the event of their choice sorority. They were encouraged to go to the other two events (if invited) to thank them for the invitation. There have been girls who stayed with us all night.
We I rushed there were 4 sororities on campus and and I received 4 invites to Preference Night. Preference Night was a couple of hours and I spent way over an hour in my 1st choice sorority and then went to the other 3 to say thanks for the invite. If you don't show up in the 1st or 2nd group of girls each sorority pretty much knows that you are not interested in them. The last sorority I went to during Pref Night was awful...all the girls were crying because NO girls came to their room until the end. They got one girl that rush and now they are no longer on campus
