Haha, same. I wonder if I hurt my chances more by meeting them, being nervous and having that awkward forehead sheen from sweating. The conference room/warehouse lights also cast a very weird glow on my skin. On the other hand, meeting the programs gave me an opportunity to write them for follow up after Midyear, and also a way to connect in the letters of intent ("Rmr when we met and we talked about so and so?").
So that being said, it could help or hurt you. I have heard people say booths get bombarded so at the end, it's all a blur unless you had a funny story to tell or are funny looking.
