I believe the answer is yes, so long as the people your with are your family.
I'm sure the answer is yes, if say you were a member who's rented a grand villa for 6-8 people yourselves/grandparents/sister etc. That and since you don't have to be staying at a
DVC resort to get the discounts, I should think you'd be alright.
