Sounds like parents are more involved in these things than just drop him off and pick him up. Is that true?
It depends. My wife and I were involved as much as our son wanted us, or when the HC/RC wanted to meet us. He was a late D1 committment, so he did go on D1 Official Visits (Fall senior year). He also went on many, many unofficial D1 and D3 visits junior and senior year. He did not go on an official visit to the school he committed to, and attended.
Our default was to drop him off and pick him up which usually meant I was off to visit the campus on my own. Inevitably, either at the beginning or the end of the visit we would meet with the HC/RC to say "hello". There were a couple instances where the HC/RC would want to take us on a tour. There was also a good chance that the conversation would lead to the Coaches office where they would discuss offers and timelines. My son wanted us there for that.
As I said earlier...it depends. My son's first offer was the result of meeting (unofficial visits) 4 times at an A10 school in Virginia. The A10 school was local, and I learned how to be a fly on the wall when I was asked to take part in the meetings. Then there was a Official Visit (Patriot League school) where my wife and I just listened to an offer in the Coaches office on pick up day. We also took part an an un-Official visit in the HCs office of a CAA school (drove 75 minutes) to listen to an offer where only my son spoke. The most interesting experience for us was at an Ivy prospect camp 8 hours away (dream school)....which I consider an un-Official visit. Ivy HC offered my son on the mound, and the HC came over to talk to me while the event was still going on. This would be the college my son would eventually select. You just never know how these things are going to turn out, but I think if parents teach their kids how to handle these situations on their own (knowing when to respectfully bring Mom & Dad into the conversation) they are much better off.
Just my experience....
