And, if looking around the various
DVC resorts at WDW, the studios at BWV, BRV, BCV, Poly, and VGF, allow 5 (plus an infant under three) because they have that extra, somewhat smaller than twin-size, bed that pulls out of a cabinet (except for the new Resort Studios at VGF which have an extra bed via a couch that coverts to a bed). AKV, OKW, SSR, BLT and CCV do not have that extra bed in the studios and allow only four (plus an infant under three).
