WE have stayed on Korcula and found it the most layed back and wonderful destination. The walled town itself is a mini Dubrovnik with little alleyways and tavernas. It is a short walk from where the tender will drop you but worth a visit. There is not a lot more to Korcula other that beaches and some small villages so I don't think a tour would show a lot. happy cruising David and Susan O'Neill.
