Have you considered Crystal Waters? Small place with 10 villas, 1, 2 or three bedroom, located adjacent to Margaritaville, but very quiet, extremely well ran operation. There is a housekeeper with each unit that keeps the place spotless, but will also buy the food and prepare breakfast and dinner if requested. That means the visitor is not out having to go out find every meal. We ate in for every breakfast, and most dinners, leftovers for lunch some days, but tried other places a few times too. I felt like I had been a guest in someone's home. I am sure they will want to explore Negril, but also have a home base that is convenient and safe. Negril Tree House has a great beach bar two doors up, and also Margaritaville next door for a quick safe place for after dark fun. Of course, they can go anywhere if they feel adventurous, but Crystal Waters is a great blend of a AI safe place, but the full dose of the real Jamaica.
