you should try thw Wilderness Cabins at Fort Wilderness . They should fit your entire party in one cabin. Plus you will have a kitchen and a BBQ grill.
I'm a DVC member. We bought our membership because of the WL. When we stay we stay at the villas but all the good stuff is at the main lodge. The only thing that I can add is the Electrical water padgent at aprox. 9:30 behind the pool in the Lake.
