I would say if you are going for just the diving, it would be a good idea to cash in the travel insurance. I was just there a few weeks ago, and yes, the reefs was still covered in sand from Emily, and it was still suspended in the water from being blown off the reefs. One dive we had vis down to about 3-5 feet. I cant imagine there being anything enjoyable about diving there now. But the diving is secondary to the people that live and work there. Like it has been mentioned before, they depend on tourism, but we need to find out where the fine line is between going back and helping them out, and going down and being in the way.
