If you come by train from anywhere but Venice island, you'd better get off at Mestre station and take the orange bus 15 (a city line which stops several times along the route: it takes about 30-40 minutes) or the ATVO blue coach (direct, about 20-30 minutes, but more expensive). If you are at the Venice rail station, walk or take a waterbus to Piazzale Roma and take bus 5 (every 15 minutes at rush hours: it takes 20 minutes) or the ATVO coach (about 15 minutes).
Useful links: www.actv.it www.atvo.it www.veniceairport.it I would probably allow longer to reach Venice Marco Polo Airport. Be aware that most European cheap flights are to/from Venice Treviso Airport which is in the city of Treviso and you should allow at least an hour for travel between Venice Train Station (or Piazzale Roma buses) to the airport.
there is a station in venice, santa Lucia.
1 hour, 15 minutes
There is no train station linking either Venice San Marco or Venice/Treviso airports to the city of Venice. From Venice San Marco airport you can take a bus (water bus) to the city or you can take a regular bus. The water bus is much quicker but costs around €10. The regular bus is slower but only costs a few euro. From Venice Treviso airport you must take one of the buses waiting outside the airport (about €10) which take you direct to the Venice city bus station.
What do you mean by "Venice Port". The main Venice station (Santa Lucia) is about 20 metres in front of the main canal.
Luton Airport at the moment has no train station. Instead to get to the Luton Airport train from Luton airport you have to take a frequent shuttle bus down to Luton Parkway station. The train is still the fastest option to travel between Luton Airport and Central London, the alternative Luton - London bus is cheaper though.
You can fly from the UK to Trieste's Ronchi airport, to Treviso airport or to Marco Polo airport (nearest to Venice). From Ronchi, you can take a bus (or taxi) to Trieste and then a train to Venice, Santa Lucia. The Trieste bus and train stations are next door to one another. From Treviso, you can take a direct bus, which leaves quite frequently, to Venice From Marco Polo, you would take a bus (or taxi) to the Mestre train station. Board there to go to the Santa Lucia stop, which is at the foot of the Grand Canal in Venice.
There are many train stations in Lisbon.The airport itself does not have one train station, but there is one close to it (Oriente Station). From the Airport to the station there is a direct metro\subway connection.
Which train station? Eastern, southern, western or airport train station? (Keleti) (Déli) (Nyugati)
Gatwick Rail Station is at the South Terminal but there is a small shuttle train which runs between the north and south terminals.
Which station and which airport? You're not helping here!
I would go by train. Trains in Europe run on time and are efficient. There are also plenty of buses. They too are good.
Luton is the nearest airport to St. Pancras International Station. The train journey is between 50 minutes and 1 hour long.
