I suppose I should have mentioned that the dive center has said people who sign up for the night dive they are planning can either come and dive for fun, or pay an additional amount and do the night dive "course" and get that certification. So, my question is - if we do that and get night dive certified, then later sign up for AOW can we count that night dive course as one of the adventure dives for AOW even though we took it prior to signing up for AOW. I've left a message asking the instructor if we need to complete any book work before the night dive, but as of yet haven't heard back from him.
