I'm guessing hundreds of thousands have used Uber in Jakarta, and in other Indonesian cities. It's just like using Uber anywhere else. Pretty much straightforward, though pick-up times can get pushed back (traffic).

The airport (CGK) isn't the easiest place to kick off your Uber relationship: best line up for a Bluebird or splash cash on a limo (it won't break the bank).

It's not a resort.
