This year CEYOC is unique for easy reach-ability by public transport everywhere. You can leave your cars at home and save the nature. You will not need them in Brno at all. The event centre, all the arenas and also all the trainings are easily reachable by public transport, which is well developed in Brno.
No need to rent a cars, no search for drivers and no annoying troubles with logistics. Brno public transport is as fast as car, but cheaper and nature friendly.
