Five of us flew to Cayman Brac for eight days of snorkelling and diving. The weather was great (although a little windy the first couple of days). I got in five days of diving and joined the others for snorkelling most days. The villa was great. It is located on the north shore and you can snorkel right there. It came with a car which was quite convenient because the dive shop is at the far west end and it made it easy to get to the snorkel sites.
The only dive operator on Cayman Brac is Brac Reef Divers. The boats are in good condition and they treat the divers well.
