That would be sweeeeeet! I will definitely visit Darden; i just don't know when yet. If you could show me around, i would greatly appreciate it!
I don't really know what the value is, although I can tell you that I attended an info session in San Francisco, and when I went in for my interview 4-5 months later, the Adcom I interviewed with remembered me from the event. Darden is definitely a place that welcomes personal contact.
If any of you are coming, send me a PM and if things aren't too crazy I'll try to show you around.
