Obviously it's in my favor to attend. In spite of the extra stress and hassle it is a good opportunity to poke around and gain insight into the program. That's not what I'm getting at. Some programs offer this evening soirree while others don't. When I know in advance I work it into my schedule. But one of my programs sent me all their interview info and then about three weeks later told me about their evening-before thingy. I've already bought my tickets and can't make it. Is this going to look bad? Will they care? Will they even notice?
