You will also find a BBQ lunch on the island, plus you can order your special drinks and use your sign/sail card, crew will be on the island offering drinks, etc. All in all, its a great beach day, you can do an excursion or just be lazy on the beach.
Been to Coco Cay. When you get off the tender you immediately see what the island is all abouy, for every 2 palm trees there is one hammock . Swimming is also great. If you chose the snorkeling, you get a short training course and away you go right on the beach. It is great.
