We were able to pick up our specially priced APs without DH there, but he had injured himself and wasn't up to going to Epcot. He was with us on the trip and called to ask that we be allowed to get them.
Other than that outlier and exception, and booking stays, there are no other benefits. At least none that can be relied on.
(Though I do feel that a case can be made for being able to pick up tickets or aps without the member there, since family members in the same house are entitled to them...but I suppose that not all Associates are family members in the same house)
