getting to Venice train station from airport

Dear Dina,
I assume you mean you are taking the bus from Marco Polo airport to Pizzale Roma in Venice, and then you are walking to Santa Lucia TRAIN STATION, to take the train to your cousin's house.
Yes, I have done this on foot with luggage, and it's quite possible. It's only a few hundred yards from Piazzale Roma to the train station. You have to cross a couple of bridges.
The only problem is that you have to drag your bags up the steps and down the steps to cross the bridges.
Have a great trip! Kerry

You don't have to go 'around the bend' into venice...could just take bus to mestre train station
see www.veniceairport.it, and http://www.actv.it/pdf/ACTV_Orario_Automobilistico_Invernale_07_08.pdf

You can do either of the above and more. As Carolyn says, you can walk it. The bridges over the canals are there but they are not luggage friendly. However, it definitely will work. Second, as above, you can take the bus to the Mestre train station and pay to ride on the train for the 12-minute ride into the main Venice train station. It takes longer and it costs a few Euro. The walk is much quicker and free. Last, you can take a ride on the Vaporetto from Piazzale Roma to Ferrovia (main train station).

Go with Randy's suggestion. The only possible route for trains leaving Venice Santa Lucia station is to go over the bridge to Mestre, where all but a few express trains will make a stop. It will be much easier to take a bus from the airport to Mestre station and catch your train there.

Thanks for your advice, everyone! Much appreciated. I pack light so I think I'll haul my stuff over the bridges to S.Lucia station; much prettier than Mestre.
