Between Las Terrazzas and Seascape is what was to have been LT, phase two. One day they will probably continue. Meanwhile the portion they completed is a thriving resort.
The Hotel was never completed and therefore could not open. It is a very interesting property and the right investor could do something fun with it.
Journeys End is simply abandoned because it got old. Same owners as LT above. Consider it land banking. Not for sale. Probably the property Shyboy is referring to as being on both sides of road.
San Pedro Scoop carried a whole story on the Essene Way, another semi abandoned property.
