To try to state the problem more clearly.  There is a matter of taste.  Certain ones have to be in English (Warsaw), Certain ones have to be in Polish (Mariensztat) due to lack of good translation.  There's a grey area in the middle.  We have to decide where the dividing line is.  Since it seems that everybody agrees that Polish is better here in most cases, we can easily and simply list the ones which we think should be in English.  "Old Town", "Home Army" and "Warsaw" as before + "City Centre".  So we can't vote simply since yes or no.  We have to list.
