I've been student hosting for my MD/PhD program every interview weekend since I started that program. I used to host MD students too, but 2 different people on my futon at different times in the week was becoming a little much

. I think staying with a student is the way to go. I went out and bought a pretty nice sofa-bed mostly because I wanted my interviewees to be comfortable (and still only one has ever matriculated here! hmmph!).
I agree somewhat with gbwillner. In particular his second point: if you're the kind of person that wants to really ask good questions and dig deep into what the school and student life is really like, staying with a student is the only way to go. #1 is kind of hit or miss. If you stay with me you might get the impression that the students here are all like me

That being said, I'm quite shocked by and scared of gbwillner's third reason. That's an extra-interview game I'd prefer not to be a part of and that doesn't happen here.
All that being said, if you prefer the hotel, ask for it. Pre-meds sometimes read too much into this process. If you have a question CALL THE PROGRAM. If you call once or twice with legitimate questions, they won't think you're a psycho. Meanwhile, if they offer you a hotel room and you want it, TAKE THE HOTEL ROOM. It's one thing to ask them if they didn't offer, but probably on the order of half the applicants will take the hotel room. They're not going to go down the list and say "friendly, friendly, GREEDY BASTARD WHO TOOK THE HOTEL ROOM X X X X X X".
I get this half number from experience. I find this story kind of funny a social engineering sort of way, so I'll post it. Over the years my school has been experimenting with the wording on their interview invite letters. Student hosting was once the only option, but it became too much work to beg the students to host week after week because too many people just don't have room or time here in the big city. That and because after first year most students get pretty apathetic to the plight of applicants

(true anywhere!). In any case, the school first started by saying student hosting was the norm but a hotel room was available. Well, that year about 75% chose the student hosting. Why? Well, through my in person conversations with people and SDN the applicants were scared that since student hosting was said to be the more common path, they didn't want to stand out. The next year, the school emphasized the hotel possibility and said that student hosting was also available. Well, about 25% chose student hosting that year. Same reasoning. So many people said they didn't want to stand out, but just take the one that looked like the usual path.
Now they're just putting them sort of equally. You get your choice of hotel or student hosting. Last year, it was more like 50/50. I wonder if the order of the words matter... Maybe our psychology applicant in the next thread over can write a paper about this
