I guess my real question is, how important is AOW for a beginner? Should I just dive and get some more dives under my belt first and not worry about it? Or is the training worth it? I can always do my AOW locally too.
I guess what it comes down to is your level of comfort. You dive to have fun. If an Advanced course will provide you with the skill-sets that will improve your diving enjoyment at this stage, go for it. If you're happy diving in your current envelope, wait and just enjoy your vacation.
I've known divers that have dove for years with a Basic / OW certification. They have thousands of dives and are safe to make any dive one could ask them to do. Certification doesn't mean what it once did, so you need to take enough training to insure you are safe. I believe every diver should be trained in rescue, so as to make them a contributing member of the buddy team. This use to be included in most training programs, but is seldom included now. Get the training you need to dive the conditions and dives you want to do and have fun!
