Yes sunblock is a must!! What i suggest you do, is come up with a list on paper, and as you pack cross off what you already have. Don't forget to bring your bathing suits, and definitely something for your hair depending if its long and curly like mine, I always have to carry around my blow dryer and hair iron! Anyway, don't forget to just have fun!! I'm hoping to do my honeymoon in a beachy destination as well.
