If you are looking for great photos on St. Maarten, then one possibly would be to go to Maho beach...that is the one that is right next to the runway. You can google it and see what I mean. You can get close up photos of huge planes, including 747's that are incredible.
You can also negotiate with a cab driver to take you around various spots on the island. Just be aware, there is only one road and it does get congested, so be sure to give yourself plenty of time to get back to the ship.
