I asked to stay with a student host, but nobody called me. I called them about a week ago (my interview is on Monday 10/24), and asked about it. The lady that answered the phone said "If we had a host for you, someone would have called you by now. Book a hotel." I got a hotel and rental car, and then I got an e-mail yesterday from a student saying "Hey, I'm your student host. What time do you want me to pick you up at the airport?" I got a deal on the hotel and car online, and I can't cancel without big cancellation fees.
Needless to say, I was a bit unhappy about the situation. Oh well, such is life.
