I just watched your video. Unfortunately, you are located in the area that had the most seagrass when we were there by far. The sandbar down to your left was one of the nicest areas though as it did not seem to collect there and the water is clear. I do think the other side of the island was generally better as well.

You are right though, they must rake it up much more aggressively like the competition. We saw people raking in front of a few villas I knew were occupied. They might rake in front of yours if you make a stink, but no guest should have to.
