I have been staying away from the site for personal reasons but I can help with this question with experience from last year.
My son had his CVW at on the same weekend as your son, last year. My son had been in frequent contact with the Sprint Football Coach and was assigned to a Plebe Sprint Player as his Drag. I can tell you that if the Academy is for your son, the CVW will solidify the desire. Below is the Schedule that was promugated for the activities last year. I don't know if the activities will be the same given the change in command and direction but it's at least a hint, FYI:

I had thought that I would drop and drive on but the Thursday evening shindig includes the parents. Be sure to feed your son, and any other foundling, before the 1730 tee off. They get nothing to eat on Thursday. The teenagers seem to have endless capacity for food consumption.
My son experienced the Chopping, Chow Calls, hazing and other, wonderful, plebe-centric events during those two days. The experience is much more "real" than the Summer Seminar. It really is a snapshot of life (or no life) as a plebe. Believe me, the CVW is a deal maker or breaker. The kids get to experience the academics, athletics and professional training that they will, hopefully, see for real three months hence.
Good Luck!
