I don't know.. we stayed prior to the Hurricane
Everything in the key's has been. The resort will get going soon. No phones, electricity, supplies are getting trucked in. I would call them in a week or two.
From the aerial views it looks like Hawks Cay faired pretty well throughout the hurricane. A Some roof damaged; a boat in the lagoon; damaged boats. They have a Facebook page but here is the web address of NOAA of aerial views from right after hurricane. storms.ngs.noaa.gov/storms/irma/ I'm sure you can always call.
We were there the weekend before but I can't imagine that it wasn't affected to some degree. The resort in on "duck key" and that section of the keys sustained a high impact. Best off contacting them directly.
