Yes — Marco Polo has its own Water Terminal, a covered dock reached from the main terminal by a moving walkway, where Alilaguna’s public boat lines (Blue, Orange, and the summer-only Red line) and private water taxis depart. Alilaguna is not a direct shuttle: it calls at every stop on its route, so a one-way ticket only covers a single continuous journey — hop-on-hop-off needs a 24h, 48h or 72h ticket instead. The Airport–Venice fare is €18 one-way or €32 return.
