Even if they intend to finish the resort, they may have to tear down the unfinished buildings and start again. They've been sitting there, open to the elements for six years. The interior building materials that were never designed to be exposed to sun and rain have probably been damaged; metal components have rusted, fiberglass insulation deteriorates from UV light,etc. If anything inside has gotten wet (a certainty in that climate) there will be mold growth that will be almost impossible to eradicate without tearing out every porous material in the building, such as drywall, wood members, carpets, and insulation. Then every surface will have to be treated to kill remaining mold spores. The roofs and air conditioning systems, if installed, are already 6 or more years into their 20 year lifespan. Finally, some of the systems that were code-compliant 6 years ago when they were installed are no longer compliant and will have to be replaced.
In the end it may be more cost effective to just start all over again than to correct these problems.
