Get there early, rent a locker if you are worried about your stuff (we just put ours on a couple of loungers, get them early too). We set up by the huge lazy River that went to the slides. Once they opened, we used them before lines got long, using the River (which is awesome). We hit the beach and aquarium later. We are a big breakfast on the ship and brought prepackaged snacks. Buy water from vendors at the pier, I think water was $10 at Atlantis, I can’t imagine food prices. Easy to get taxis back and forth.
