I am writing an article for a recreatioanal scuba diving magazine on planning and implementing a successful dive vacation that involves two (or three) generations when the youngest participants are teens or young adults (not young children and old enough to dive.)

I need an expert to provide real-world advice on the joys and potholes of such a trip. What do people need to know about the practicalities of intergeneratioanal travel to make the trip a success?
