I have not yet been invited for any interviews but I have relatives in several areas where I'm applying (NY, Boston, Philly, SoCal), have the time and would like to visit campuses and just get a feel for them. It might make me reconsider some schools that I have on my list, and might give me something more to talk about if a secondary asks,"Why our school?" I know most med schools don't want to hear if you're in town and want to tour the campus, but what kind of experience do you all have? Was it worth visiting ahead of time?
