whats the difference between a CVW and an athlete being invited for a visit? Do athletes typically stay with plebes in their sport?
what is a CVW? a campus visit? is it extended to all candidates?
CVWs (Candidate Visitation Weekends) are typically offered to either highly qualified candidates and/or those who already have appointments. They are organized by CGO and you are assigned to a plebe (of same gender) for the WE. Not all candidates are offered CVWs; not being offered one does NOT mean you won't receive an appointment.
CVWs are now more involved and organized today than they were in my day. I think you now show up on a Thursday evening and spend Friday attending classes, sports, etc. with your plebe escort. You stay in that person's room and eat at his/her table. You depart around Saturday at noon. The idea is to give you some sense of what life is like as a plebe. People who did NASS may still be offered CVWs. I recommend doing both (if offered) unless finances preclude it.
Athletic visits are for recruited athletes. I don't know much about them other than they are organized by the athletic dep't and I believe are generally similar to CVWs other than that you are assigned to an athlete from your sport and attend team practices.
I'm not sure what you mean by "campus visit." It could refer to one of the above or it could be you simply showing up at USNA. You can take a tour and meet with CGO (at certain designated periods -- check usna.edu for details).
I don't think students are offered both athletic and CVW visits as much of the WE would be duplicative.
