We have six people in just our immediate family, so I've done quite a lot of calculating the costs of this. The best deal while staying on-site always seems to be getting two (connecting or adjoining) rooms at a Value Resort. If discounts come out or you're willing to pay the extra, 2 rooms at a Mod would be even better... as they have more amenities... better pools, incl. slide & Hot tubs... more space in rooms, etc. The DVC resorts are not cheaper and neither are any of the suites. In fact they can often more than double your cost for accomodations.
