What do the little ones (i.e., 3 yr old DD) do on Castaway Cay? I assume they're shaded, etc. and I read somewhere that they're not taken into the water. For safety reasons, I just assumed we'd keep her with us-- and we probably still will. But if I can slip away for an "adult beverage" with DH on the adult beach for an hour or so, that would be fun, too!
