Most readers and posters here are long time visitors. The last thing on most vacationers minds (other than us here and a select few) this season or even most likely next season is "Hey, let's go to a place that was just devastated..."
I think most of us here also know just exactly what island time is and when things are publicly announced they always seem to be a little premature. It's just Island nature to be a bit over optimistic on real timelines or deadlines.

If you stop and think of the amount of contractors and professionals that will have to be there to build in the amount of time most businesses predict is a logistical nightmare. Especially when most are working on their own homes themselves. The shipping in of building supplies, the lack of sand needed for concrete, to wood or steel supply to the amount of machinery needed.
Add the recent announcement placed by VROMI to locals that no business, home or otherwise can be rebuilt until it is assessed by the Govt. for safety to rebuild, and all will have to apply for permits and go through proper building approvals before swinging a hammer. There are not enough locals to handle the adjustment in regards to insurance, and when will they pay?
Not enough skilled staff in VROMI to expedite any permit. How fast will you be approved to rebuild?
If these things are taken into consideration, then the knowledge we all have here is that It's really going to be longer than anyone wants or anticipates.
