It depends on how you plan to reserve the villas, on a package, direct from WDW or by renting points from DVC members. Renting points would be the cheapest way but it depends if you can find someone to rent you enough points for the length of your stay. Obviously the studios will be cheaper than the 1 or 2 bedroomed villas, which were you thinking of booking and how many guests would there be?
We love the BCV and always stay there on our WDW holidays so I would book the villas over a regular room any day as we love the resort and we love having a full kitchen and plenty of room (we book the 2 bedroomed dedicated villas and there are 4 adults in the villa.)
If you have any more questions just ask, the BCV is my favourite resort.
