New Passport Law:
All Visitors are required to have a valid Passport when traveling to and from the Caribbean.
U.S. and Canadian visitors are requred to have a valid passport Tourists are granted admission (upon arrival) as tourists for 14 days (maximum 3 months, upon request). A $20 tax is imposed upon departure from the Juliana Airport. Those arriving on the French side may stay up to three months, but a visa is required for longer stays. A 3 euros departure tax is included in the price of airfare for those leaving from Esperance Airport.
Hotels on the French side typically add 5% occupancy tax per person, but a small gratuity is greatly appreciated for exceptionally good service. Restaurants also add a service charge to the bill. For taxi drivers it is customary to tip between 50 cents and a dollar, while porters at the airport usually get $1 per bag.
Choice of clothing should be casual and comfortable but neat. Swimming attire is not appreciated in hotel lobbies or for walking around town. At night dress remains somewhat informal, but jackets and shawls are recommended since casinos and restaurants can get a little chilly.
For getting around from place to place a car is virtually indispensable although most hotels offer shuttle service to the casinos on the Dutch side of the island. Rental agencies are located at both airports and at the major hotels. Driving is on the right side of the road, and most of the roads are in fairly good repair. Motorcycles and mopeds are also available for hire.
