One thing I think Riviera design did well was removing the balconies on the living room portion and pushing the exterior wall to depth of balconies off bedrooms. Functionally it made the living room longer and that helped by adding more space to both feel bigger and add extra seating perpendicular to the sofa.

But some resorts with balconies on exterior wall at least have more room than Poly has.
Here's VGF as an example:

Poly's living space comparatively looks cramped and has less seating. They added some movable seating but where is it supposed to go when the Murphy bed is down? There's not very much room to rearrange furniture.
