We charged it to the tab we had for the day, but two chairs and umbrella were around 30 E. As far as sitting on a towel, I think you can go way down to the end, since all beaches are public. But frankly, why would you?? It's kind of a trek to get there to AM. You can go MANY places around the island and put down a towel and be by yourself if you want. To ME, the reason to go to Anse Marcel is to partake of the excellent food there. And if you do that, spending 30 E for a chair for the day shouldn't be an issue. OR just go for lunch, and you don't need a chair on the beach at all. The beach to ME isn't that great, although there are not any waves normally, so it's easier for someone who is not very mobile to go in the water. The sand is pretty dark and coarse and the view, to me, isn't nearly what it is at many other places.
Your mileage may vary.
