Two additional points about inn rooms vs. studios:
Because the studios are adjacent to 1 BR villas with a connecting door, they can be somewhat noisy due to neighbors in the unit next door. We have had this experience twice at VB. Our last stay was in an Ocean View Inn Room and was much quieter. YMMV.
There are a small number of inn rooms that have a king size bed and a sleeper sofa rather than two queen size beds. These are a "squarer" shape than the other inn room so this furniture combination appears to fit better. If you are traveling without children, one of these rooms may be ideal. We had one for our last visit (in January this year) and loved it. Next time we go to VB, we will request this, realizing of course that it cannot be guaranteed.
