It's perfect for you. It is a resort on the island of St. Martin in the French Antilles (just opposite the island of St. Barts, where all the stars go LTHE)
The Dutch side of Saint Martin is known for casinos, shops, but not as beautiful beaches. Part French St. Martin is known for its beaches, water sports, food, landscapes, etc.
The station is called Alamanda Resort. It is friendly for families and casual. Alamanda Resort is a nudist resort, although they are often on the beach topless. But right on the beach at the beach in front of Alamanda is a totally nude beach.Now, it is also a station, but you do not have to stay in and out naked. The water is clear and warm and beautiful.
There are three different seasons pricving to Alamanda. The high season is in December and January because of holidays and the weather perfect. The season average price is from February to May and that's when I was there. Fewer young people partying on the beach but lots of people. The cheapest time to go is June to October because that is the Hurricaine season, so I do not want to go, then. I am told that some shops cvlose then....
