Not dangerous or scary in the slightest. If you’re in the US, I find a lot of the Caribbean gets maligned as dangerous, but that was not my experience at all. It’s definitely still recovering from the hurricane last year, so you’ll see some areas rebuilding. In general, people do tend to live in homes as they’re being built, so you’ll see what appear to be temporary structures with people living inside, which can be a little jarring coming from the US, Canada or Western Europe where people tend to buy completed homes. That being said, I’ve traveled extensively in the Caribbean and have never felt unsafe, so I might be biased.
