It really is a nice accent. I spent my most formative years in the Caribbean, and I still have a bit of an islander accent when I'm around others who have one. There's a gentleman who works at a Publix near me who is from Trinidad. The first time I met him, I only caught a slight hint of his accent. I asked him about it, and when he told me where he was from, we both immediately started speaking in full-blown island accents.

I also had two friends during my time in the Caribbean who were originally from the Outer Banks. I don't remember which island exactly, but they both had noticeable accents that were unlike anything I had ever heard at the time.

Watching videos about the various Outer Banks accents definitely reminds me of them.
