Cruise ships in Venice can dock at one of two basins; Marittima or San Basilio, the dis-embarkation process is different for each basin.
Also the route to reach the Peoplemover Train that will take you from the port to Piazzale Roma in order to catch a Vaporetto along the Grand Canal will vary depending on where you berth.
Check out our Cruises to Venice page for more detail on how to visit the main attractions in Venice using public transport.
So it is always useful to see where your cruise ship is likely to dock when in Venice.
