We are cruising on the 18th of this month and we have the excursion for catarmaran Sail & reef snorkeling in Nassau scheduled because it is offered for the whole family but we were wondering if anyone has every done this and if so what do they do for the little ones as far as snokeling. My daughter is 5. Also has anyone been lately to either castaway cay or nassau who can tell me how the degree of the water is?
