Thanks amileduan.

In this case the render time wasn't too bad. I was able to render with my (mini) render farm (one i7 machine and 2x older machines which added together make another i7 equivilent speed).

The total time per frame over this mini network was quite quick - somewhere between 40-50 secs a frame.

What keeps the render time down is the low poly people with simple shaders. Only the walls reflect the lights and there are not that many lights in the scene.
