Virak Buntham Sihanoukville Siem Reap recent customer reviews

The bus was overbooked which resulted in me being kicked out of my seat and forced to share a single with someone else, after being yelled at for staff for someone that was not my fault and I had fully paid for my seat. Not only that, but it was overcrowded onto my seat with locals and staff yelling loudly at 3 am when everyone was trying to sleep. Absolutely awful experience, did not get what I had paid for at all.
