Jakarta to Yogyakarta: Airport Transfer & Train Timing!

Planning my fourth trip to the incredible country of Indonesia!  This time, I'm flying into Jakarta at 9:30 am on Saturday, but heading straight to Yogyakarta by train. My target train departs from Gambir Station at 2:00 pm.  Is that enough time to make the transfer from Soekarno-Hatta International Airport (CGK)?  Should I book the train in advance, or risk it?  Any tips on navigating Jakarta's airport and transportation to Gambir would be greatly appreciated.  I'm particularly interested in hearing from fellow travellers about their experiences with this route, including the best way to get to Gambir efficiently and avoid potential delays.  I'm also keen to hear about any must-see attractions or hidden gems in Yogyakarta that I might have missed on my previous visits!  Let's make this trip the best one yet! #Indonesia #TravelTips #Yogyakarta #Jakarta #TravelPlanning #SoutheastAsia #TrainTravel
