Mapnik tries not to draw icons and labels on top of each other.  So as
you add more detail to an area, some features may be "dropped" in
favor of others.  It can be a bit unpredictable sometimes.

Osmarender, on the other hand, doesn't care what overlaps what.  So
high-detail areas can become rather cluttered on that renderer.

I think it's most important to get the data in, and tagged right.
Even if Mapnik doesn't show everything, other applications looking for
the amenities you've tagged will still be able to find them.
