I believe DizBub was saying that the combination of (a) lower points at OKW
and (b) the fact that OKW is so large, so there are lots of rooms usually available, means that (c) OKW is a top contender when looking at what
DVC resort to choose for a large family.

OKW was the first DVC resort to be built. They had no idea at the time that the whole timeshare thing would turn out as big as it currently is and, I don't believe, they knew exactly how people would use it. The rooms are, I'm pretty sure, the largest of all the DVC resorts but it's not within walking distance of any parks.
Like any hotel, the DVC timeshare resorts have limits on the number of people you can put in a room. A Studio allows 4 or 5 (depending on resort) and a 1-Bedroom allows 4 or 5 (again, depending on resort.) You would need a 2-Bedroom unit to support 6 individuals. The number of points a rooms "costs" is dependent on four main factors - what resort, what type of room, what view and what time of year. A Studio will cost a certain amount, a 1-bedroom even more, and a 2-Bedroom more than that. So the lower points at OKW is a plus. The size of the rooms compared to other resorts is a plus. And the fact that there are lots of rooms in the resort is a plus. (The views and time of year don't matter much, in terms of the question "how many people in the party" so there's little reason to go into those.)
