Beach an Bar Mahogany Bay

Are there any beaches with a bar on it or near in within walking distance of the port? Are there any activities you suggest for my older teens 17-18?

Mahogany Bay is Carnivals man built beach. You will get off the ship in port and it's a short walk over to the beach and there's plenty of bars and a huge beach. They do have things to do there that teens would enjoy (but you would have to rent) and a place along the boat dock (not the pier) if they are in to snorkeling.

We don't really care for the "fake" beaches too much and like to actually get out and see the "real" areas in port. But after we went to our place, once we came back, we spent a little bit of time here.

HERE is my link to my pictures of Mahogany if you are interested.
