Here is what my visit looked like: Arrived around 10am, received admissions briefing - question and answer session, was met by a plebe who took me to lunch, attended afternoon classes and then practiced with the team I was interested in, eat dinner in the mess hall, hung out in the dorm - had some down time while my plebe studied, slept, woke up, went to morning muster and breakfast, morning classes and then left at noon.
Overall, a great 26 hours. I learned a lot about KP through hanging around with the midshipmen.
Glad to answer any more questions that you may have.
