Hi Robert If all you want to do is to create a map with points inside each polygon, you could do a SUM grouped by the polygon ID on your location data and then link the result to the polygon layer. You can now do a thematic map with "dot density" - just make sure you have 1 dot = 1 location.
This also saves you from geocoding and moving the centroids.
