So, $500 apiece. Interestingly, many liveaboard trips in Raja Ampat are longer than a week. From what I've seen online, prices vary, but base prices for a 10-day might run over 6 grand, but sales are fairly common. In a nutshell, a 10% 'cost of trip' trip per person might be in line with that, or a bit more.
Now, if people are tipping 10% of trip cost to the crew overall, and additionally coughing up a half-grand apiece tip to the guide alone...and some people think this is the usual mainstream (not just high-end boats) practice for customers on Raja Ampat liveaboards...then that needs to be brought out on the forum, because I would not have known that!
