Hey, congratulations on the interview!!! To answer your questions, I stayed at a hotel about 10 minutes away from campus so I wouldn't stress about traffic the morning of the interview. No student housing was offered which is understandable.
I used uber/lyft everywhere, which might be beneficial on interview day because you may find other applicants heading to the same airport and split the fare. Use your own discretion with who to trust lolol. I almost used a rental car, but I actually saved more money by ubering/lyfting.
I also recommend flying in a little earlier the day before the explore the campuses because there isn't a tour offered on the interview day.
Feel free to PM me with any questions! 🙂
