A very bumpy ride taking longer than it was meant to, did get there in one piece and I suppose bus company not to blame for bumps on the road, not for the faint hearted.
Bus departed from Sion circle 1 hour late, arrived 5 hours later. 14:30 insted of 9:30 . You will not get neither water nor dinner, like it is normal in Thailand. Pickup location wrong!!! There are not 3 pickup locations at Sion circle]!!!
