Vince - check out The Golden Sunset on beach road (across road from Alfreds Ocean Palace). You could rent two adjacent double rooms with a shared kitchen at a very reasonable price. Great Jamaican property owned by the Arthurs family from way back in the day when Negril had neither roads or piped water. The owner, Ray Arthurs, is one of the founding members of the Negril Chamber of Commerce, and a very nice man. This is where SLP usually stays, and she has posted pictures in some threads over the last few months.
