I'm a OL also, but I've already been to a couple open houses for admitted candidates. They both had a "student panel" in which current students answer questions, sometimes with no administrators present. I found it most helpful to ask questions during that time that only current students would really know or admit. For example, I find that all of the schools seem to boast about there excellent career services, but the students had a different opinion. That way I'm not making my decision or forming an opinion based on exaggerated information found in the school's bulletin. It also gives me a heads up on what to expect at the school I decide to attend. I know that at school A, I can expect little help if I'm seeking jobs or internships outside the region, so I can take my own initiative from the beginning.
