We have stayed in OKW (many times), VWL, BCV, BWV, SSR and HHI (one time each).
Only one we lack is VB.
My DVC sister has been in all of them except BCV.
Before we joined DVC, my sis would only stay in OKW, LOL. When my family goes to WDW now, though, if her fam goes too she usually tries to stay wherever we're staying - hence, we've gotten her to go to both VWL and BWV that way! OUr next trip is set for OKW, but maybe we need to go to BCV instead and see if we can force her over there to complete her rounds, haha!
We still haven't done Vero as a family; I'd really like to try it, though. Someday!!
