This map shows all three sections - The Moon (left most) the Sunrise (center) and the Nizuc (far right).  If you click on any of the sections, you can see the names and locations of the restaurants, shops, discos, etc.  This map also shows the shapes of the pools - from what I saw, Nizuc shares the Sunrise's huge pool.  I believe I was told the pools are approximately 1/4-1/2 mile in length each!!  They are spectacular...
