St Maarten Island spans over 37 square miles, and it is not possible to explore the entire island with public transport in just one vacation. To roam the entire island, you need private car rentals to save time and money. In this article, we will discuss the need for car rentals on the island. Here are a few reasons below: 1. Sint Maarten is divided into two parts (French and Dutch) with a border without any official checkpoints. Travelers can easily go across the island without any restrictions and cross borders anytime. 2. Renting a car gives you dining flexibility; you can visit any restaurant any time on both sides of the island. 3. Cost effectiveness is another factor. You can save time and money with car rentals and use that amount in duty-free shopping at Philipsburg.
