From most European capitals, Naples can be reached by plane, arriving directly to Capodichino airport.
From there, bus n. 14 goes to the main railway station, from where all other bus services depart.
Bus 3S, marked with symbols of plane, train and ship, takes to the tourist harbour, which is very close to the conference venue.
Tickets for these buses can be obtained form the tobacconist's inside the airport, or inside the station if you arrive by train.
There is also an Air Shuttle service, which is privately run but quite reliable. In any case, Capodichino airport is actually within the city's boundaries, so that taking a taxi is not prohibitive!
The airport is connected by commuter buses to the city centre by ANM or CLP lines to Piazza Municipio. From Piazza Municipio take C25 bus towards Mergellina and get off at Piazza Vittoria. Walk towards west to the seaside and turn on the left on Via Partenope (you'll have the bay of Naples on your right). The Congress Venue is 300 meters on the left at Via Partenope, 36.
