Here's a way to look at it.
There are WDW resorts. These include different prices for views and for Concierge level stays and also suites.
There are DVC resorts. With the two aforementioned exceptions, they are priced the same within each category (studio, 1 bed, etc.) at each resort. They do not include any concierge levels or suites because they are "Home Away from Home" options.
Some of the DVC resorts are also attached WDW hotels -- WL, BC and BW. They are two seperate "resorts" that share some amenities including pools and check-in desks.
DVC members may also use their points to book stays at WDW resorts. There are different points required for the different views and for concierge.
However, once a DVC resort and a WDW resort become "sisters", a DVC member may no longer book stays in the hotel portion using points. Yacht Club is not considered part of the "sisterhood" so it is still available but Beach Club is not.
Hope that helps.
