I've both stayed with student hosts and stayed at hotels the night before my interviews. The definite advantage of staying with a student host is that you get to learn a lot more about the school. One of my hosts even took me on a pre-tour of the school the day before my interview, so I wouldn't get lost the next day, and I've had the opportunity to really get to interact with the students in an informal setting. The disadvantages are that you usually don't get an actual bed, and it can be hard to arrange morning schedules especially if there are more than two people living in the apt. The times that I've stayed in hotels, I slept much better, but I feel that I didn't learn as much about the school and its students. My suggestion is to stay with student hosts if you can but try to find one who lives alone or has only one roommate and ask them a lot of questions. Most of the time they are in no way affiliated with the adcom, so you are free to ask them ANYTHING! Hope this helps.
