One route tells the story of a city thoroughly: using the Grand Canal as an "open-air museum," linking architectural history, the history of the People's Republic, and commercial trade history into a single storyline
The train station is the starting point: board the boat directly after getting off the train with zero connection cost, especially suitable for half-day transfer travelers and passengers carrying luggage
Dual perspectives from onboard and onshore: view palace facades from the boat (along Ca' d'Oro and Palazzo Contarini del Bovolo), and observe the city's texture onshore (Ponte di Rialto)—the perspectives complement each other
