Hi there, Belinda!
I love, love, love the benefits that come with my
Disney Vacation Club membership. With three families traveling with us this past summer, we truly saved a bunch of money by using the
Free Parking Member Benefit.
I'm continuously reaching out to
DVC Member Services, because I have gotten varying answers myself to this question, however, general consensus is that as long as you are staying on DVC points, and the person in the car is staying in one of the rooms using points, there is not a limit to the number of cars you can bring. This means that as long as all of the 14 of you are staying in the rooms on points, there shouldn't be any issues with bringing cars.
We had three cars on our last trip, and there was no problem at all with parking for those. All three vehicle owners were listed on our reservation.
This sounds like you are going to have a great big family adventure! I wish you the most magical time.
Anna
