This route seems like a convenient one for us to get to our apartment near the San Marcuola vaporetto landing. are there any other routes and/or methods we should consider instead? Also, is it possible to remain on the Alilaguna boats after they reach the end of their routes and begin the return trip? It occurred to me that if we remained on the arancio boat until it passed the San Marcuola landing on the RETURN trip, we would effectively get a tour of much of the Grand Canal for the price of our Alilaguna ticket. My guess is that we would need a round trip ticket, but I thought I would ask here to get clarification. Thanks.
