I’m just off of Mariner & we were at Coco Cay 2 days ago. Symphony was also there & all beds/cabanas - everything was sold out. It was pretty full there - not much quiet anywhere that i could see. We headed back to solarium & that was the best choice by far for us. Quiet & only a few at the pool.
we did a beach bed once before south beach was completed. others beds were pretty close and not very private. wished i hadn’t bought one to be honest. lesson learned
