Another thing to keep in mind is that OKW and SSR are not attached to an existing Hotel and you can not walk to any park. BWV & BCV allow you to walk to Epcot and MGM and are connected to hotels. VWL and AKV are also connected to hotels but do not allow you to walk to any of the parks. All four offer multiple dinning and entertainment options through the hotel that you do not get at OKW or SSR. However, some sections of SSR are close enough to DTD that you can still get multiple dinning options with in a short walk.
Finally, remember the size of the resort. OKW and SSR are very large. This means they have the most members and thus the most resales. The laws of Supply and Demand apply.
With all this said, we love OKW. I actually think that it is very relaxing. Large patios / decks, larger rooms, soft colors, quiet pools, no shared buses, etc make it a very nice place to stay. You should try to visit each of the resorts to be sure you buy the one best for you though. Keep in mind that a few more dollars a point really makes little impact in the long run so if you prefer BCV, then you should purchase BCV.
