Ok. I have 3 days on Ko Chang in Thailand, a small-ish island with not a lot to do but relax and explore. Should i try to cram in my PADI open water certification course, and see if I can shorten it in any way through online prep and/or using my previous dives, for about $500 USD? Or should I relax, do maybe ONE discovery dive with an instructor for $100, and enjoy my vacation while I'm there?
Cons for PADI: I've seen it cheaper elsewhere, I shouldn't really spend a lot of money right now since I have no job at home, and I don't want to be rushed on my vacation.
Pros: Getting certified in THAILAND!, I may be bored otherwise, I DO want to dive (and one dive is still pretty pricey), and I have a credit card I can use in a pinch.
