I am heading to R4 in October. Passing through Singapore and Jakarta. First trip anywhere in Indonesia besides Bali seven years ago. We will be staying mostly at homestays, and mostly on far-flung islands, then at a rustic "resort" on a tiny island, i.e. not ATM's beyond Sorong and probably Waisai. So we will need to have those piles of cash. I appreciate the post in old thread re: carrying a portable safe et al. and am planning on that. I have read that the Jakarta airport ATM rate is bad. Is it better, or worse, than changing money from Wells Fargo in the U.S. - anyone know? I'm not interested in trekking into Jakarta during my layover. I am wondering whether the Singapore airport currency exchange is worth considering. I have a Schwab debit card and of course will have that along, but I've had enough experience to know not to depend on that. Of course I'll have USD as well. How do I set things up so I get the best exchange rate and have all the IDR I need? My questions are particularly directed to those of you with experience in the last couple years, especially going to far-flung areas where there really is no ATM. Thank you in advance.
