It's because most people "camp" out of view of the webcam. And the beautiful pool is rarely crowded. People tend to stand and chat in the water at the shallow end.
You may spot people in the now-enlarged shelter smack in the middle of the camera. Later, in October, you may spot me there, sitting with a beer writing the novel which started there in the summer.
And, of course, Nafsika is very close to the beach, and if you are staying at the hotel normally you would go out for lunch. The pool is the only pool we ever use; it's quiet, lovely garden, and often you will see house-martins dipping down to catch a drink from the water.
Thirteen days to go!
