Lots of well thought out suggestions. I wish I had this thread when I started. I have now been on over 40 tours, and retired!~ YAY!! Most of my suggestions are covered, but two additional things D1 (now a college junior) looked for on visits, 1)she liked to see kids on campus wearing their own school shirts. If there were lots of students wearing their own schools shirt it meant kids liked their school. 2) She always wanted to go to parts of campus the school didn’t take you on the tour - to see the worst parts of campus they weren’t showing you. 3. My D liked to see an undergraduate focus. She had her own criteria for deciding, it wasn’t always based on numbers. 4. My D liked to pick the tour guides, and pick the ones “like her”. Those were the guides she would talk to after the tour.
I also think we didn’t worry that my D would be homesick, and so when she was, we were really grateful for the support the school provided through the RA and her freshman advisor. So for D2, I always ask about Freshman support. It is quite common to have an adjustment period for freshmen.
