Congratulations warpath !
When I was there I had a very relaxed interview. You only meet with one interviewer there, which I think is a benefit- you only have to worry about winning over one person and you have time to talk about everything you want to addess. I would suggest staying in the dorm room and going to the pizza party the night before your interview, so you can meet some students.
Good Luck ! 🙂 🙂 🙂
