Scuba and Dream:
People are looking for a single tank night dive, even though they haven't dove in years, quite often in Kona. Most operators have gone to two tank dives only.
Part of the problem you have here is that the night dive has the reputation of being the "must do" dive here, and when someone who hasn't dove in quite a while decides they gotta try it they ask around about what the "must do" dive is and they hear "manta dive" from message boards, other divers, even stores on the mainland. Few take time to think a night dive isn't a good idea as your first dive back in the water after a long layoff.
I used to work the one tank dive 3-4 nights a week several years back for another operator, Matthew's description is pretty accurate. Now that I'm on my own the policy is a late afternoon dive followed by the night dive unless you've dove with me recently. I have to expain why I require the first dive to a significant portion (say a quarter or more) of the callers looking specifically for night dives.
