From Cruise Terminal

What to do when you arrive at the Cruise Terminal

You can reach Venice Piazzale Roma from the Stazione Marittima Cruise Terminal on the People Mover, the automated monorail train that connects Piazzale Roma and the Tronchetto terminals.
Tickets may be purchased directly at the automatic ticket machines located at the entrance to the People Mover.
When you reach Piazzale Roma, it is just a short walk to the ACTV landing stages, from which the main public transport waterbus routes depart in all directions and for all destinations, along the Grand Canal or the Giudecca Canal, or following the circuit of the outer circle waterbus routes.
