While I appreciate your concern over the cost of chairs at Coco, they are not 20 euros per chair, but 20 euros for two chairs with an umbrella. That includes a nice beach blanket for each chair, a bottle of water, and consistent beach service including fresh ice all day. Definitely not the cheapest place on Orient, but we think the value is worth it. And as much as I love Friars, including the beach, the calm water, and most especially, the restaurant....sorry, but the chairs there don't even remotely compare to those at Coco. We enjoy both beaches while we're there, but I'm surprised that you would choose Friars over Coco if you had issues with your back. Regardless, I'm happy you were able to find a beach that met your needs; just wanted to clarify the cost of the chairs.
