Just checked into Le villa after spending 2 nights at VSJ. The wifi situation here seems to be much better. It looks like I can post photos directly without converting them.
Saline: A tiny bit in the water and some old dry stuff on the sand. Pretty typical for an ocean beach. If you didn't know there was a seaweed crisis, you would have thought nothing of it.
