My advice is not to use true ambience. I have gotten away from using the premium settings and found ways to simulate them the quality is better and the render times are much lower. Also needs more light on my computer . The attached picture used 21 lights to get the effect there. If you look closely there are soft shadows and there is ambience but on areas hidden it is still dark. Experement more with the light and spending an extra hour on lighting might save you many hours rendering. Download the zenith lighting system and do what I did disect it then experement and make your own light rigs.
