It turns out that my DS' mother is friends with married couple who recently relocated to Annapolis. I assume that the plebe sponsor program is for plebes who really have nowhere else to go in Annapolis, and that plebes that have family or friends there may visit them just as other plebes may spend time at their sponsor's home. Is this the case, or can plebes only visit official sponsors' homes? When do these visits occur, i.e. only during regular liberty? Thanks in advance!
