Where in Sicily are you going?? Please tell us more!! Sicily is incredibly beautiful. Whatever you do, make sure not to miss the Cathedral and Cloisters in Monreale, the temple and amphitheater in Segesta, the beaches of Terrasini and the beauty of Etna and Taormina. And that's only the beginning!

The Sicilian dialect is different enough from "Italian" that linguists have said that it should be considered a separate language of its own. However, you shouldn't have a language problem if you speak Italian. Most Sicilians do as well.
