The Royalton Saint Lucia Resort is located in the Caribbean, on the island of St. Lucia; about 1h30 from the airport. It is a hotel with all-inclusive service and upscale comfort. The resort has three sections, a section for families in the main complex, the Diamond Club for superior service (with exclusive pool and reserved areas in restaurants) and the Hideaway, an exclusive quiet area for adults. There are several a la carte restaurants and depending on your package you have to book or not. There is a bar before going up to the lobby (which is upstairs, accessible with escalators) where there is usually live music at the cocktail hour. There is wi-fi throughout the site, satellite TV, non-motorized water sports and a fitness center. The site is beautiful but the beach is small and there are rocks.
The US dollar is accepted everywhere, no need to have the local currency.
If you travel with children, there is a supervised club for them with a lot of activities, there’s also another for teenagers between 13 and 17 years old.
If you want to rent a car, consider that the roads are sinuous all over the island.
