We went cross country for a HA school camp after the RC had seen my son (RHP 2020) at both the Arizona Fall Classic and at a HeadFirst camp and strongly encouraged him to go to their prospect camp. This was in the fall/winter of his junior year. The PC had seen video from the camp, PBR showcase, etc. but had not been at the events to see him pitch live. My son had already confirmed that he had the GPA and SAT score required to be considered for admission. This was a school that had been on his radar as a good fit so we took the plunge and spent money on airfare, hotel, car rental and the camp fee (which was very nominal). In my son's case, it paid off. He received an offer that he accepted. However, the expense was not insignificant so I would recommend that you ensure most of the pieces of the puzzle are in place ahead of time (and combine with campus/admission tour).
