Does anyone have any experience taking a non-diver or novice with them on a live aboard? If they are content topside with a book and headphones, is it still worth it? My wife is a novice and is not drawn to the water like I am. She would maybe take advantage of a dive or 2/day and spend the rest of the time hanging out on the boat. Looking at Belize or Roatan Aggressor and looks like itinerary has minimal time, if any, on land.
