Our ports of call are Aruba, Curacao, St. Maarten and St. Thomas (originating in San Juan). We have never visited Curacao and St. Maarten and were wondering what's the best way to get a good "taste" of these islands - excursions, taxis or rental cars? We are not beach goers or big shoppers. We're more about the local culture - markets, history, architecture and geography - natural attractions. And we are both big shutterbugs!
