The link on CN's "map & 360^ view" page is decent for identifying most locations (highlight cursor over each description to see where it is on the map). http://couples.com/negril/map.php
Also this thread has a picture of the map on CN's watersports board. It is one of the more detailed maps we've seen, but the lower resolution of this picture (due to shrinking down for posting on the MB) may make it hard to see. http://couples.com/mb/showthread.php...ril-resort-map
For the past couple of years, the envelope given to guests with their keys has a decent map/legend printed on it.
