Hi Milan,

The main differences between St. Marten and Curacao is the size. Curacao is a large island and is rich in architecture, shops and restaurants. The cons of Curacao is that these places are all over the island, and not in one place. You need to rent a car! The beaches of Curacao are a definitly a pro. There are a lot of and each of them are very beautiful. As for St. Marten, it's relatively small, but a lot to do and realy nice restaurants. A pro of St. Marten is that neighbouring islands are just around the corner and are worth a visit. The beaches of St. Marten are not as good as those of Curacao.

Good luck!
Justin
