Select 'View a List of All Destinations' from the 'Find Destinations' drop down menu. The list defaults to DVC & Disney Resort Hotels. You can change 'Destination Type' to see other point charts.
The member site, until fairly recently, had a direct link to the DVCpoint charts under the "Plan Vacations" tab on the main page. When it updated the Resort Availability Tool last September, Disney IT, true to form, decided that members could not stand such simplicity and removed that link.
Fortunately, they are very easy to find from the DIS. Look for the blue tool bar near the top of the any forum pager and select the "DVC" option. Scroll down a bit and select the link for DVC Point Charts. (Brings you to the same place as the direct link posted by BobNed).
