This is only a beach of white sand, free of any tourists (at the time of the picture) : looks simple and corresponds to a certain idea of luxury for me :).
In the CI a swimming pool with a view on caraibean sea, an other idea of luxury.
Absolutely, I completely agree: Being alone on this lovely beach is a pure luxury of our time. It's wonderful to "play" Robinson Crusoe sometimes ... with the luxury to escape the island whenver you want - haha. The CI is great too, the pool looks really nice and special, it has a lovely view from there too. This looks like a true paradise.
