One day
Start early in Piazza San Marco before the crowds, and take in St Mark's Basilica, the Campanile and the Doge's Palace with the Bridge of Sighs behind it. Walk north through the Mercerie to the Rialto Bridge and cross into San Polo for the Rialto Market and a stand-up lunch of cicchetti at a bacaro. Spend the afternoon riding the number 1 vaporetto the length of the Grand Canal, then finish with a spritz along Cannaregio's Fondamenta della Misericordia as the day-trippers leave.
