So, it stated between 08:00 and 16:00. I got picked up by 07:30 and got back around 19:30. Not because expanded experience. Just beacuse poor planning from the trip guide company. I had to go from Canggu to like 4-5 pickup points because they had planned wrongly (no one to pickup at some pick up points, just wait for no one). I was in Ubud like 10:00, after a looong morning in the car. We left Ubud maybe around 16:30 and took 3 hours to get back. Just because the car had to drop people off in other areas like Sanur and so on, not really along the way. So, I spent 12 hours of this supposed-to-be 8 hours activity in the car for approx 8 hours (also between the sites). The sites themselves are really just tourist attractions. No autencity at all. The guide was quite good though. He did his best.
