I've been accepted to only one program with decent funding, so I'm certain that I'm going to go there. That said, I'd really like to go to the Open House weekend, but they are not funding travel expenses, and the plane tickets are rather on the steep side. How important is it to attend one of these events? Should I just suck it up, pay with a credit card and go? Or is it something that isn't a big deal if it's missed? I'd really appreciate any input.
