DVC owners have multiple favorite resorts. But don't need 250 points at all resorts. We started with only 75 BLT points think it would be an every other year or every 3rd year stay. Then we stayed and loved it. So we've added on there.
When the Poly is built I could see wanting 50-75 points there for 2-3 nights here and there with BLT being our main stay.
Points are poitns at 7 months, so many just want the advanced booking window for a few nights at prime times periodically.
