I am aware rates vary for military and DOD personnel who stay at SOG based on factors such as rank and service class. Nevertheles, I believe someone who goes only every two to three years and can reserve SOG should have second thoughts about joining DVC. Overall cost is likely going to be less, both in the short and long run, with SOG. Thus, the only reasons you should consider DVC is if you actually have a great desire to own and stay in one or more of the DVC resorts (and understand that you are not going to be getting something that costs less than SOG) or you are soon going to be giving up the ability to use SOG by leaving leaving the service or DOD.
