Hello- I am a parent of a Stevens student.
I have added some links at the bottom to help you in your planning. I do not think that Stevens would let you stay on campus. The W Hotel is a very short walk from Stevens, and you could take the PATH train in to visit the city (also a short walk).

It’s a bit expensive but very convenient.

I would call and talk to someone in admissions regarding which tour would be best for you and your daughter. Stevens seems to be very interested in admitting women and I would mention that you would prefer a female student guide.

If you are interested in speaking with someone in our office regarding International Undergraduate Admission, please contact the Office of Undergraduate Admissions at 201-216-5194 or admissions@stevens.edu
Good luck and I hope you get more answers~
