Sandals is for Adults only. You would need to goto Beaches Resorts (Family resort). The Beaches resort in Turks is one of the top 3 resorts in teh caribbean. But it is NOT cheap!!!!
Beaches @ Turks and Caicos is the only Sandals resort in T&C. But yea, he's right, Beaches = for kids, Sandals = adults.
I was at Beaches T&C last month, and the water was a bit rough. Also, to book the snorkeling trip..do so in advance, we tried to book a slot when we arrived but everything was booked..
it's also very expensive if you're not paying some sort of employee discount rate, about $800 a night per room
