I can't quite remember.... There were some posts a while ago about it.
I think the sandbar/kiddie area is closed in November. I thought it was up until Thanksgiving. Then the lazy river section would be closed in December but open for Christmas. Then from Jan 1st to Feb 25th the slide and I believe the major portion of the pool would be closed. We are going to be there Feb 20-25 so were a bit sadden by this news.
Do a search on SAB rehab both here and on the DVC board and I bet you will find the info.
