DH and I are going down in January with plans for another trip in October. This is the first year we are thinking of getting him an AP. DH is not on the membership (purchased before we were married) and we have different last names (I never changed my name). What do we need to show in order for him to get the DVC discount on the AP? Is his driver's license showing we live in the same house enough? Do we need to bring a copy of our marriage license? Thanks in advance.
