Always a 1BR here. We're splurging next year, taking my mother's side of (divorced) family for her birthday. We're booking a GV for the five of us those two weeks and can't wait. Since there's just DH and myself at the moment (ok, plus dog) we can't see many GV stays in our immedite future...
We did purposely buy enough points for two weeks in a 1BR during the time when we are most likely to visit (late April/early May) so that is meant to be our accommodation unless our family situation changes.
