I can tell you that my son's overnight at WP left such a positive impression that he is very much sold on USMA, and has accepted his appointment. Prior to that he was really struggling between USMA, USNA, USAFA and ROTC. Although he would still like to do an overnight at USNA, I think it is largely so he has no regrets about giving Navy a fair shot in his analysis. Frankly, I would like him to maintain an open mind at this point, and, to me, USNA offers so many career options in both the Navy and Marines, including fixed wing flying, that he should give Naval Academy full consideration. At the same time, I must admit that my wife and I are both pretty sold on West Point too, and just get a great feeling about him being there.
My son's host plebe was sick, and quarantined to his room, so a buddy of that plebe took over. My son actually was passed around a bit, but he really got a good opportunity to talk to several cadets, and got a good perspective. Its not that he "had a blast". That wouldn't be the right description. He did enjoy it, but more than anything he felt it was a real good fit for him, and he felt a comfort about it. He appreciated what he saw, and respected those he met. He very much felt like he belonged there.
