The following not only allow 9 but have sleeping places for nine in the 2BR: BLT, AKV (other than "value" rooms), and OKW, which each have a an extra twin bed that pulls out from a large chair in the living room; VWL 2BR lock-offs (combined studio and 1BR) which have an extra Murphy bed that pulls down from the cabinet below the TV in the studio; VGF dedicated 2BRs (can only be a 2BR) which have that Murphy bed in the living room; VGF 2BR lock-offs which actually allow and sleep ten which have that Murphy bed both in the living room and studio; most of the 2BRs at BWV which have a Murphy bed in the studio of the 2BR lock-off, and by next April all of the 2BRs at BWV will have that arrangement as its refurbishment is ongoing and should be completed by then. BCV will be refurbished next year to add the Murphy bed to the studios and when done its 2BR lock-offs will sleep 9. Poly has no 2BR villas, only studios and the 2BR bungalows which sleep 8, buts it's studios have the Murphy bed and you can get connecting studios and thus sleep up to ten.
In other words, SSR is becoming the lone WDW resort whose 2BR villas will not sleep nine.
