+1, there is no real disadvantage in using lots of small polygons, but there are a lot of advantages in doing so, mainly that the structure is simpler and easier to edit and refine, the rendering (or other data usage) of small areas is faster because more efficient (because you only have to look at what is in your screen bounding box and do not have to care about huge multipolygons with (potentially) hundreds of ways and (ten)thousands of nodes which extend way beyond your area of interest. The key advantage is that they keep complexity low and ease editing and maintenance, while huge multipolygons are a nightmare. In case of complex borders (intent with more than ~2-4 nodes) between neighbouring areas I'd use small multipolygons to avoid complex overlapping ways. cheers, Martin
