Thanks everyone for the advice. FOr those asking, my profile is not up to date. I have well over 100 dives by now. I've been doing the cenotes for years now and am looking to take it up a notch. My plan is to do the cavern and intro to cave training on one trip and then the full cave either on a second trip, or when I'm moved! Thanks again!
I would take each class separately and spend time practicing skills in between the classes. Becoming a good cave diver is not so much about increasing conceptual knowledge (although there are lots of new concepts to learn) as it is about acquiring new skills, many of which must be internalized so that you have good habits to rely on. There is only one way to get to that level of diving, and that’s repeated, controlled practice.
If you’re going to live down there and dive in the caves regularly, (I’m jealous!) then you should also learn to dive sidemount. That’s another class, no matter what anyone tells you. What you might consider is doing cavern in single tanks (that’s the norm) and then sidemount, and do a lot of practicing in the sidemount configuration on cavern dives. So many of the skills can be practiced in open water as well, and these are the things that typically determine your success; buoyancy, trim, propulsion, basic task loading exercises, etc. After you’re feeling pretty confident and comfortable with SM in the cavern zones, then you can take intro. I would then spend quite a bit of time doing intro level dives without an instructor, building good habits of the basic skills; line and team awareness, communication, line running, problem solving, all with excellent buoyancy, trim, propulsion. To do this right you’re talking about several weeks of time. Then you can tackle the higher demands of full cave and focus on the complex navigation requirements, dealing with restrictions, and the generally higher standards of diving at the full cave level. Living down there will make this approach really convenient.
Going from an OW diver to full cave diver in 10 days is not generally a successful strategy. There are exceptions, but usually the result is you learn too much too fast and can’t retain it all, and develop poor habits from lack of repetitive skill practice.
In terms of instructors, I like very much the culture at Under the Jungle, and it’s pretty convenient to Playa. Nat and Vince are both really top notch instructors and the shop really has a deep learning and constant development culture. Nat’s producing excellent teaching materials too.
