If you can find someone to rent you
DVC points at a good rate you're looking about about $250-350 a night for a 2 bedroom villa. (depending on time of year, price per point, which resort, etc) Also that would be Sunday through Thursday because Friday and Saturday nights are about double the price.
Three rooms at a value are probably going to run around $300-380 per night, maybe a little less if you've got a code rate in value season. So the prices are comparible. But I will point out that a 2 bedroom villa only gives you 2 bathrooms, when obviously 3 value resort rooms will give you 3 bathrooms. And the 2 bedroom villa also means 4 adults would share the room with 2 queens and the other 2 adults would take the king bed... or someone would take the pullout sleeper in the living room.
Take a look at the floorplans and pictures. That will help you decide which is best for your group.

Have a great trip!!!
