Yesterday I added Get around Brno page to the LibreOffice Conference website. There you can find comprehensive information about public transport in Brno, how to buy tickets, how to get to the hotel/venue if you arrive by train/bus/car/plane etc. All accompanied with maps and pictures of described places. So hopefully no one will get lost on their way to the hotel or venue, or struggle purchasing tickets.
If you’re coming to LibreOffice Conference 2016, definitely check it out. You may also want to download the page for offline usage in case you won’t mobile data.
