I am a big fan of continuing diver education and taking courses to broaden you competence and comfort levels, BUT.. I am an even bigger fan of practical experience. Many divers never do any certifications passed their basic open water ( my wife Debbie, for example) but are excellent divers. Debbie has over 200 ocean dives and I would rather dive with her than anyone. Of course, she has had the benefit of a private DM on every dive (me)! Enjoy the trip, gain experience, and as area interest s you or as you feel a need to improve in a certain area, take an appropriate class.
