*If you're in Jakarta with limited time, you can still see Borobodur since all you have to do is take the overnite 1st class train to Yogyakarta (the capital of Central Java), then take the +1hr. bus to Borobodur.

Indeed, you have to go 1st class 'coz it's so fast & comfortable like Eurorail of western Europe yet almost empty that you have a lot of room to yourself thereby allowing you to sleep well on that overnite trip.

Also, going 1st class will enable you to arrive to Yogyakarta early next day giving you plenty of time to see Borobodur & the smaller ruins nearby, then make a return trip back to Jakarta that evening. It may sound fast-paced & crazy but it's for tourists with limited time.
