People will tell you that the Greek islands are not what they were, but they’ve been saying that for a long time. In 1878, Edward Lear complained bitterly that Paleokastritsa in Corfu had been overrun by badly behaved English tourists, and Odysseus probably disapproved of all the new villas put up in his absence by the suitors. There are more than 150 inhabited Greek islands and fewer than 30 ever get seriously overcrowded. (Has anyone ever been to Agios Efstratos?) Even the busiest islands have places where you can escape the crowds, and sometimes the crowds can be fun.
