Just an FYI for future reference, if you would like to go to an "off the beaten path out island" sometime, you don't have to take a propeller plane to get to Cayman Brac. Cayman Air has jet service to Brac twice a day from Grand Cayman. And during the high season you can fly directly to Brac from Miami, bypassing Grand Cayman.
There's not a lot to do on Brac but there is a small, interesting museum, wildlife preserves, Booby and Parrot sanctuaries. And although the bluff is at higher elevation for climbing, caving, and hiking, most of the habitation is in the flat areas and there is plenty of easy walking and bicycle riding. The people are friendly, they speak English and crime is very rare.
I understand that there are snorkeling sites but I haven't tried them. We usually stay at the Cayman Brac Beach Resort and there is a huge infinity pool and a lovely little beach for sitting and relaxing, but it is not a good swimming beach. There are other beaches on the island, including a very pretty public beach.
Interesting possibility. One of my sisters stayed there on her honeymoon and loved it. She was not a diver but is an avid snorkler. They had been a couple for 20 years before they married so they probably had time for lots of varied activites
