Um, just so we compare apples to apples (that is studio to studio, not studio at SSR to a regular room at VWL)
VWL Studio $305 $349 $415 $465
SSR Studio $279 $309 $359 $399
Different rates for different seasons
So yes, you can stay cheaper at WL than SSR, but I personally would pay more to stay in a studio.
Good point. Probably better to leave WL out of the discussion since the DVC rooms have always been ovepriced anyway. (BW and BC cash rates are MUCH higher than WL--there's no way that the DVC point charts should have been equitable between the three.)
Back to AKV vs. SSR. AKV has two DVC room classes cheaper than SSR. Even with the added appeal of the savannah, some rooms / seasons in that class are the equal of SSR. Why? To offset the lack of demand at AKV.
