This is just IMO, so take it as that, but I don't support taking cavern alone. 2 days (often 1 diving, 1 classroom) isn't enough time in the water to begin diving overhead environments. I would seriously look at taking a GUE/NAUI Fundamentals of Technical Diving course and then taking either C1 or Cavern+Intro combined. That way you're getting 4-5 days of skills, then 4-5 days of overhead procedures.
