The staff service is good, but just a little story.
We arrived at a little past 17:00. We bought tickets for the Roro Jonggrang show, but because the event was still quite a long time away. So we went a little bit to the Prambanan view. Indeed, the area there is for Shinta Obong. We just wanted to take pictures with our family, but it seemed like we were being watched all the time ha ha ha.. just to learn from this, next time we have to be in the area where we buy tickets.
