Other reasons, primarily personal safety.
I’ll be with my parents and boyfriend at all times. Is it safe as long as I’m with someone?
I personally would not suggest it unless it is a well lighted beach and there are many people around and then only with using caution and extreme common sense. My common sense would tell me "NO" and I have been going to the island for 28 years.
I guess here comes the obvious question: is there a lot of crime on the beaches?
Not trying to be a smart-a$S but you will get responses on this board from seasoned visitors and residents, some local and some transplants. Trust me, they know what they are talking about.
Not a lot of crime on the beaches but don't put yourself in a position to be an easy target either. It only takes that ONE time of being in the wrong place and then your vacation could be ruined.
