My kid is a senior, so she’s been doing lots of interviews and online info sessions for schools. Her feedback is that she’s actually preferred the interviews and discussion panels with students vs. admissions officers, it helps give her a better idea of what the school really feels like. Some schools have shot way up on her list after a student-led interview. I’d suggest looking for the online student Q&A sessions and student panels as a reasonable alternative to visits. Also, reddit thread have some AMAs with current students that might be helpful.
