It's not quite the same as USNA.
An overnight visit at USMA, basically the equivalent of a USNA CVW, is only authorized for candidates who have received either a Letter of Encouragement (LOE) or an offer of appointment.
Visits run from ~8:00am on day of arrival until 12:45 the next day. So, it's only one night in the barracks vs 2 nights at USNA CVW. You can't schedule a overnight visit starting on a Friday. You can do it in the middle of the week, e.g. Tues-Wed.
There may be other programs for minority candidates. I wouldn't know about those.
I think you can schedule day visits without an LOE or offer of appointment.
