Check the scheduling with the bus line because even if your website offers 7 AM, they didn't even have a scheduled trip at 7 AM. Good thing we arrived earlier so they accommodated us at 6:30 AM trip. No notice, advice or disclaimer. POOR SERVICE.

My first impression for cross the border gate was good with mekong express, surely i will recommend to my friends, but my second bus from phnom penh was not good, ac too hot.. but overall was excellent
