Marriotts NCV avg summer week rental = $2200
$2200/15 ($/pt)= 146pts required to rent a full week
146pts at $100/pt = $14600 add on(remember, these are "rough" numbers)
i think the going rate for a platinum week at NCV is around 16K and like other high demand weeks, very hard to book a summer month even as an owner.
.
once again this would give me the flexibility of owning more DVC points which i would always use and allow me to stay at other non-dvc resorts without having to deal with trading. best of both worlds

it seems like summer weeks at high demand non-dvc resorts are always available for rent.
