Please remember that all this is a tentative date, but according to the football schedule Parent Weekend will be Oct 8-10 (maybe 11th). This is a holiday weekend (Columbus Day) and should be a 3-day weekend for the NAPSters. This is a definite do not miss weekend if at all possible. This is usually the first overnight liberty that the NAPSters will have (although this is always subject to change).
I would not count on the rest of the calendar being release prior to July 27th.
There is a new command at NAPS as well as a new incoming Supt at USNA so being flexible on many areas as far as any potential overnight and getting the entire 3-day weekend liberty is definitely needed.
Hope this helps.
