The busses were quite okay, just the Place in the sleeping bus was a bit small for a western guy.
The coordination was a bit confusing in Phnom Penh and we didn’t knew what to do.
Trip from Ho Chi Minh to Phnom Phen was smooth however the bus a little bit dirty. Passing through the borders was smooth as well. However when I arrived at Phnom Phen I was asked to ride a tuktuk going to the van terminal then when I was at the terminal I thought we will be leaving by 1530H but for some other reason we left Phnom Phen at 1700H which I was not given any explanation at all.
