Hi I'm looking to book train travel between Jakarta and Yogyakarta with my family when we come to Java in the summer. I've seen that there is a train with luxury cabins but these are private, single/individual cabins. We're going to be a family of four, two young kids. I'm assuming there aren't private cabins for a family of four. No issues being with other people but my girls can be loud so we would like to have a bit more of a private space. Is this possible on this train route/ journey? We prefer train journeys so don't want to fly.
