At all DVC resorts, there are no connecting rooms EXCEPT studios and 1BR's....and they only connect to each other.
There are a few (at most one at each resort) cases where a 1BR has 2 connecting studios- which will then comprise a 3BR. I have stayed in one of these at VB and asked where the extra door connected.
There are no 1BR's which connect to anything but a studio and vice versa.
