msbinky ~ glad to hear your family had a nice time on the catamaran snorkle excursion. I will be able to make my reservations in 3 weeks and I'm trying to decide what our family will do (me, DH, DD15, DD8, DD5). None of us (except DH) are great swimmers so I am hesitant to book this one. Do you need to wear life vests in the water?
