Hi all! We are headed to GC next week for a week on 7 mile beach. It is our first trip "south" and we are looking for any pointers on how to avoid sunburn and the like while spending as much time as we can either swimming or snorkeling. (We live in Canada, so we will not have seen strong sun for over half a year.) Some of the specific things we are wondering about are: what is the best clothing for snorkeling; recommended sunscreen number and/or brand for salt water activities and how often to re-apply; if we are snorkeling, is it only the back we have to worry about or does the sun get at your front one way or the other; and are there certain hours of the day that we can stay out of the water while not giving up the best hours to snorkel. (I should mention that neither my wife or I are real early risers by nature, but we will try to adjust our lifestyle if this is really the key!) Answers to these any other tips you may wish to share would be much welcomed!
