I visited Dubrovnik for 3 days in April 2014. It is definitely one of Croatia's highlights so I was happy to be able to enjoy the city without the crowds from the cruiseliners. That said, it doesn't mean that the city is ever empty apart from night time perhaps. Still it is well worth exploring the narrow streets within the fortified city. The highlight of my visit were not the city walls although the view was magnificent but the best view was definitely from Fort Lovrijenac.
