In case anyone is planning to go to these two beautiful temples in one day, it is possible, though exhausting. We only spent one day in Yogyakarta, but we loved everything about the town (a lot, lot more than Jakarta). We arranged a pick up from the airport, went to the Prambanan temple and then to Borobudur. We were dropped off at Malioboro at around 6 pm. Our driver was very kind and helpful.
