I've been hearing so much about Half Moon Cay. Never having sailed with HAL before, I guess it's a silly question to ask anyone to describe it, but can someone tell me...What does it offer for a couple old broads in their 50's and 70's?? I live on a beach so snorkeling, parasailing and that type of activity isn't important, but do they have hammocks and shade to just "lollygag" for awhile? Will I need to take any cash or credit card onshore with me to purchase anything other than trinkets if I choose? Since it's HAL's island, can everything be purchased with my HAL card? These might seem like silly questions, but sailing a new line brings new questions for me!
