We visited about 10 schools applied to 8. Son17 did not like touring schools, he hated every tour we went on. Found them boring and was annoyed by most of the tour guides. We did better by just walking around and checking things out ourselves, and attending an info session if we liked the place. We did not do tours or info sessions at his “safety” schools.
I don’t think I’m going to visit as many with son19, maybe visit more after gets some acceptances back.
