Just back from Grand Cayman on the Brilliance of the Seas. The diving and snorkeling is back to normal, but many of the boats were damaged or lost. Be sure to book it ASPA after booking your cruise, as many of the tours were sold out. We were the only ship allowed in port and even then, infrastructure was limited.
We toured the south side of the island and the devastation is unbelievable. I will try to post pictures later.
