You'll use a tender (small boat) to get from the ship to town. Just look for a taxi (most look like a mini-van), and tell them you want to go to the beach. Trust me, they are waiting on you. You"ll have no problem spotting them. They will take you north on Church St. to the Seven Mile beach area. From the beach, you will have a great view of the ship. When you decide to leave, there will be taxi's waiting to take you back to town. One "tip" I will mention is, if you're the first to board a tax (van), they will wait for it to fill up, before they leave. I know you mentioned that you're party is large, but just something to keep in mind for the one's that have only 2 in their party. They should look for a taxi that has someone else in it. The water on the beach was crystal clear when we last visited.
