What is best piece of advice you ever received regarding college selection process for your child?

Do as many college visits as you can! We even did college visits instead of vacation for spring break of junior year, and over several long weekends. Son kept saying he could see himself being happy at every school we visited, which was a good thing. But it wasn’t until we visited the last school over Labor Day weekend of senior year that he found a clear #1, applied ED, had a very early admission decision, and he was done.
