I am the only owner in my family and we regularly travel as a group of 8. At first the CM said two people would need to stay back since our group did not have a second
DVC member. I responded with, "but ... we're all staying together in the same 2br villa?". She checked something on her computer, then happily let us all go up. Not sure if this was pixie dust or not. (She had already swiped my DVC card or typed my name in, so maybe she was able to verify where we were staying.)
