David’s DVC is a popular choice on the boards. If you go to his site, you’ll be able to see the cost in terms if points and dollars on his site for your dates. Keep in mind, that doesn’t mean there is availability. It’s just meant to give you an idea of what his rates are.
ETA: Pay attention to the room configuration when looking at DVC. For example, AKL Jambo’s 1 bedroom standard accommodates 5, but is made up of 1 king bed, 1 double sofa bed and a sleeper chair. I don’t think it would not suit your needs. Not to mention, only 1 bathroom.
