I had scheduled a tour following my Vision experience this summer, and had a scheduling conflict with picking up our rental car and trying to get back to campus for the tour. We ended up having to cancel at the last minute. Will this be kept on my record with Admissions?
It is possible, but not in a bad way. They do make note of who visits campus, and since it was a scheduled tour, that was most likely noted. It might also have been said that you were unable to make your appointment, but that is unlikely. Definitely try to visit again, and apply !
You might write a brief email/note to your admission officer. You can let them know how much you enjoyed the Vision experience and mention that while logistics forced your to cancel your official tour, you are grateful that got to see the campus and get a great feeling for the school during the time you spent there. If you can get back to campus you can always reschedule an official tour (in which case you can mention in your note that you plan to reschedule).
