My guess would be that the least crowded would be OKW and SSR since they are further away from the parks than the others. I know during
free dining these are the villas that people have been upgraded to to make room for more package trips at the values. I can say that the BWVs and BCVs are usually full since that is where we stay each Aug. We have been at the BCVs this past trip and our upcoming Aug. trip since the BWVs were not available.
