We frequently travel on Mekong Express and felt this was the most unsafe trip we have experienced. Traffic was heavy and the driver repeatedly sped and overtook unsafely including on the verge of the road (I.e. on right side of vehicles). Disappointing.
Made it from Siem Reap to Battambang but in pretty bad condition due mainly to the very strong and bad gasoline/exhaust gas smell. The bus should be immediately checked and fixed. Otherwise the staff at the office was really nice and professional.
It took us six hours to get from PP to SH though traffic was not too heavy. Would be helpful to update the journey time as I almost missed my boat to Koh Rong.
Very long wait after border procedure and no communication at all. My guess is that one of two passengers had some visa problem. No one said anything to the other passengers and we were left waiting for more than 1 hour. Inspector disappeared.
This was a very manageable four hour journey. The seats were comfy and could recline well. The air con was adequate. We were given bottles of water and we had a comfort break at a little oasis en route. It was nice to watch the world go by.
