I'm not sure what kind of scripts you're feeding your tour guides, but a fellow student noticed an undergraduate tour guide telling a crowd of prospectives and their parents that there are no graduate students at this school.
I'm well aware that you are conflicted in what sort of image to put forth--is this a research institution or a liberal arts college for undergrads? Like a lot of people with seemingly contradictory aspects of personality, I'm sure you can integrate both. But if you have to present one side in attempt to recruit people, at least don't lie about it.
Sincerely, One of your supposedly non-existent graduate students.
