I would think the EPCOT resorts would be the best. No only do you have four in close proximity (BWV, BCV, Swan, Dolphin), but it also has the boardwalk, itself. You can also go to that minitaure golf place near these resorts, and the gas station is close if you need something quick not available by Disney proper.
Since EPCOT is right there, you could easily make dining reservations and DHS is a short boat ride away for additional theme park action. EPCOT's firework shows are also fairly visible. This location is also closer to the interstate, should you decide to visit other offerings in Orlando.
A distant second would likely be a DTD resort, especially SSR, since it is on the golf course. DTD offeres the shopping and a variety of restaurants.
Of course, there are the non-WDW
DVC resorts waiting for you. VGC allows for a nice vacation in the LA area. HHI and VB would be great for beach destinations, and we don't want to forget Hawaii.
You could also use your points to explore some of the five-star resorts around the country or trade into RCI for a week in another country. maybe a cruise would be nice, sometime...
Lots of options for you!
