Laws? Etiquette? All of Jamaica is a bit of a free-for-all, and in most towns (e.g. Lucea, Sav) parking can be an issue, but I've never had a problem in Negril because it is full of hotels with mostly-empty parking lots. Occasionally a security guard will give a hard time if you're not staying there, but usually they're chill. However I no longer drive in Jamaica for a variety of reasons. It's much more efficient for me to get from my house to Sav on bicycle. Long bike ride to Negril (but I've done it). One great thing about bicycle is there's never a problem parking it!
