I'm headed there in July. The Westin reopened last week. To quote them:
"By and large, the resort will be better than it was before the storm because all of the furniture and much of the equipment will be new. There will also be new grills, water fountains and shade sails on the hillside, and patio and balcony furniture. Some of what is new will not be visible to owners but is of extreme importance. Most of the drywall had been damaged by water, and all the damaged drywall has been replaced. The HVAC cooling ducts were contaminated and have been replaced with new ducts. We also have new and improved fan coil units, specially constructed for the resort, and not only will the air conditioning be more efficient, but also the humidity in the units will be reduced to a much lower level than before. Fire alarm and sprinkler systems are also being upgraded."
Most of the beaches are apparently open, albeit with some debris. I haven't heard anything yet about the diving.
