After rearranging things with the gguide I'm planning on using in Java he has the following suggested:
DAY 1 ARRIVAL FROM DENPASAR BALI, GARUDA AIRLINE
• Arrive at the airport
• Pick up service
• Drive one hour to Borobudur
• Hotel check in
• Overnight at Manohara Hotel

DAY 2 BOROBUDUR - FULL DAY DIENG PLATEAU
• The temple is 200 meter walk from your room
• Morning visit the temple with tour guide
• 08.30 Hotel check out, full day tour to Dieng Plateau
• Drive through villages, nice views, mountain, volcano, agriculture.
• Also see local people, farming, sulphur spring, color lake, ancient temples
• Lunch time will be at Wonosobo regency
• Drive back to Magelang for overnight
• Overnight at Berg View

DAY 3 MAGELANG - SOLO
• We drive to Solo Via Selo (between Merapi and MErbabu volcanoes)
• Visit Sukuh and Cetho temple
• Drive to Solo and enjoy the ancient Solo city
• Overnight at ROEMAHKU Solo.

DAY 4 MORNING SOLO CITY TOUR
• Visit Mangkunegaran Palace, Museum, Flea Market and Batik village
• Lunch time is in Solo city
• Afternoon, drive back to Yogyakarta and visit Prambanan
• Visit the temple is 2 - 3 hour
• There are many hidden temples there
• Proceed for Ramayana Ballet performance (Tuesday, Thursday, Saturday) or will see the schedule
• Overnight at Phoenix Heritage Yogyakarta

DAY 5 CITY TOUR
• City tour Yogyakarta
• Sultan Palace, Water Castle, Traditional Batik and Silver home industry

If I pull out the hotels and pay for those separately, and eliminate the sunrise tour at Borobudur, I get a price of $432 for 2 which includes the admissions and ballet tickets. He has put a tax/service charge of 10% on everything. Is this customary for Indonesia? Is this his profit? I know there is 20% tax on hotel rooms. I would then stay 2 nights more in Yogya giving us a day and half of free time to do what we want.

I think this is a fair price, don't you? The guide, Wiedy will personally drive and guide us at Borobudur, Prambanan, and Yogyakarta. The driver out in the country will speak English.
