Suggest you find a shop and/or instructors with whom you are comfortable and explain your goals. It might be a matter of hiring an instructor as a mentor. Or it could be Scuba Reviews. A Scuba Review has you repeat most skills from Open Water. You might find that one or two sessions is sufficient, and could couple that with a dive package for practice. GUE would improve your skills, but might require a change of equipment to BP/W.
Sorry, what is BP/W?
Diving and trying to help collecting garbage or building artificial reefs sounds cool too.
@boulderjon So GUE fundamentals is almost the same as the TDI Intro to Technical Diving?
Thank you all for you replies.
Seems like the best way to do this is to just chose a place where diving is cheap and there are lots of schools/good instructors and just go there and talk to people and try to get a good deal.
From what I read Koh Tao and Gili islands would fit? I have been in koh tao, so I think I prefer to go to a different places just so I see something different, but koh tao was nice, and the plane ticket is cheaper.
Roatan/Utila sounds nice too, but maybe too expensive? Maybe diving is better there?
Are there any other places like this?
