My interview was pretty last minute last year so I didn't even ask about student hosting but they did have a hotel on their campus that was pretty reasonable and there is a shuttle to the interview the next mornin, or you could walk if ur not in heels like I was . . .
They send you a list of area hotels via snail mail, along with your other interview info. Just make sure to make a reservation ASAP because the cheapest hotels ($50-$60 I think) book up fast.
