(Note Oneworld's RTW products, mainly the Oneworld Explorer, are the main topic of discussion on this board, so research on your part needn't be too complicated.)

It looks like typical economy fares in mid-summer from AMS to CGK return can run in the €1,200 - €1,500+ range, although you might have access to cheaper fares. An economy class Oneworld LONE3 RTW ticket with travel beginning and ending in the Euro countries has a base price of around €2,100. That would get you up to 16 flights through 3 continents (Europe, Asia, North or South America) over 12 months from the first flight.

However, the same ticket, but with travel beginning and ending in Norway, carries a base price of €1,490. You could probably get from AMS to OSL for way less than the €500 or €600 you'd save on the base ticket. (Note kids under 12 get a 25% discount.)

With that ticket, you could fly to CGK via Doha or Helsinki + Hong Kong, or various other routes served by Oneworld airlines. Visit your people or places in Indonesia, then maybe do a side trip to Japan or Malaysia or wherever, then when it's time to head home, you'd cross the Pacific, maybe to Vancouver, Dallas or San Francisco, then to AMS. You'd still have many months' validity for the ticket, so you could use the ticket for a trip to, say, the UK or Spain, or back to Doha, before ending back in Norway before the 12th month has ended.

Of course, if you wanted to linger in North America, which includes Central America and the Caribbean, you could do that on the way back to Holland. Here's an imaginary map showing a possible "minimal" RTW route:



And here's one that includes places like Vancouver BC, Los Angeles, Miami and Aruba.



The point being, with a "master plan" you might be able to leverage considerably more travel out of your out-of-pocket Euros. Maybe worth some research and "what if" speculation.
