Are you talking about the SunTerra Polynesian Isles resort?
If so, I can tell you a little:
My parents traded a timeshare week, and we stayed (my parents, DH and I, and DS [age 5 at the time] there 2 years ago in January.
We were in a 2 bedroom unit, on the second floor. Very spacious and typical 'time share' decor. Plenty of room for all of us.
There is a washer dryer stacked outside in a closet, and they are shared by 2 units. One pool was down for maint, but the other one was right next to our building, and it was lovely.
Our longest drive to get to ANYWHERE on WDW properly was 10 minutes.
If this is the place, we enjoyed it very much, and I think $99/night is a GREAT price.
