I stayed at the Student Guest House, which is literally a block away from campus. It's owned by a family that is very nice and helpful. You get a bedroom and your own bathroom, not a lot of frills but everything you should need to get yourself a good night's sleep and up & out in the morning. The owner makes you a very tasty breakfast and then gives you a ride over to campus.
Basically, it was the easiest thing for me to do, was only $85 and was worth way more than that to me. No cabs, no trains, no hotel check-in, and breakfast included.
I highly suggest it!
PS Did anyone else here interview Oct. 18? My status still says "Your interview has been scheduled...."
