I have a potential group leader here checking the place out, and he's asked me what to do when you want to dive but the weather's too bad (like now). In other words, you haven't planned to be off the island at sparrow fart because you want to dive, but 8:30 comes around and you're told "no diving". What to do then? Let's assume for the sake of argument that we're dealing with people who don't just want to hang around bars all day.
