The experience was worth seeing, despite I almost had a heat stroke and I don't remember about 15 minutes of the show. The amphitheater has stairs, which you sit on and those are being heated by the sun all day long. For tourists not accustomed to Bali temperatures and humidity: ALWAYS have some water with you and try to have a hand fan - it really helps when you're about to lose consciousness, for seemingly no reason at all. Overall experience is REALLY WORTH IT.
