I need TA's to give me more info regarding Jack's night snorkel. What happens between 5 and returning at 8:30 - 9:30? How far ahead should you take sea sick pill if you are concerned that you might get ill. I get cold easily. How long are you actually in the water? Should we have a big meal at noon or should we eat light? Yes I am a little nervous but knowing details helps me out and I understand it is a tour of a lifetime.
