Hi Damian,
I still would not use categories for anything location based, not with that many categories, there are much better ways to do things.
With the location manager for example the locations , country, region and city will be added by default. Further to that you can manually add neighbourhoods, and if this is not enough location information then you can manually add other fields which will be much more efficient than categories.
Lets take for example here: https://www.google.co.uk/maps/place/50°03'32.5“N+19°56’20.2″E/@50.059029,19.9382439,18z
With Location manager you would get the following info added by default:
Country: Poland
Region: Lesser Poland Voivodeship
City: Krakow
And you could add your own neighbourhoods to that also.
What more info would you need for that location?
Thanks,
Stiofan
