This place views their guests never ever catching a glimpse of their other guests as their main mission I think and they pride themselves on being the best in the biz at this. We pretty much have not seen anyone except us on the grounds. It is supposed to look like all this is just for you apparently. After a day or two it kinda sucks actually.
And every second review on Tripadvisor aparently mentions it too:
This is how 'crowded' the beach is at all times (this is about a twentieths part of it but the rest of it is as empty as this piece).
