I'll start by saying that every diver, regardless of experience, is a beginner in a completely new environment. How well the diver can cope with new and different and possibly unexpected conditions depends in part on the diver's experience (the toolbox they bring to the dive) and the resources they have available to them.
A couple of years ago, my husband and I did a trip to West Palm Beach in Florida. We both had hundreds of dives and a LOT of training before we went, but we had never done "hot drops" (negative entries) into deep drift dives before. We paid very close attention to the briefings, and we had friends with lots of local experience with whom we were diving, who could give advice and accompany us. We were far from elegant, but we managed and had a ton of fun. Had I been a brand new diver in that situation, I would have been pretty apprehensive, and I don't know that things would have gone as well.
If you will have patient and experienced local buddies on your trip, I don't think you need to dive with a professional. But if you are going alone and don't know anyone, and you are brand new, it might be best to hire a companion for a dive or two, until you get your sea legs, so to speak. If your certification was done in inland fresh water, then the ocean itself will be new to you, and you will most likely have a better experience if you have a "certified competent" buddy whose attention is entirely on helping you have a good time and stay safe.
