Other options available: tricycle, horse carriage, metered/non metered taxi, jogja bus, rent bicycle/motocycle. If you are a solo traveller, there are ubermoto/grabmoto where you can ride a motorcycle just like uber/grabcar.

9. Some attarctions like Kalibiru have different entrance ticket fee price on weekdays vs weekend.
10. Try to plan your trip to visit places in the morning and evening because afternoon (12-3pm) in Yogyakarta can be very hot. Dont forget your hat, sunblock and water bottles.
