There are two main reasons why you shouldn't overlook this canal-laden city. First, in the future, large cruise ships will not be allowed to cruise past Piazza San Marco and the gleaming Basilica di San Marco. Second, most ships dock overnight in port, giving guests an opportunity to explore a city where no cars, taxis or buses are allowed. Transportation is solely done on public water buses, private water taxis or on foot. To escape heavy crowds, make your way across the bridges along Riva Degli Schiavoni, where the locals hang out to dine and shop at the Arsenale. If you want to pick up a souvenir, colorful ceramic carnival masks are plentiful, as are glass figurines.
