We always stay in the Waterfront Chalets. They are the closet to the beach, in fact on the beach. Price in May is 364 Euros per night.
The link below will take you to the Club O website. Look for the tab toward the top of the page that says, "The Club." Hover over that tab and you will see a drop down box that you can click on to get a map of the Club. Hover over the various buildings to see what they are. There is also a tab for "Rates and Availability."
