dvc member golf question

[chainkid]

My husband and I do not golf but our son and daughter do. They also share respectively our same names. When you present your cards to pay for membership can they get the golf membership as they are my children. They are both over 21 living at home. What ID do you have to show??? Not trying to cheat but feel since they are my immediate family they should also get benefit after paying yearly golf membership?? Any one help me here
