ATV takes the new road to the north Cambodian-Laos border. You are left to cross the border yourself. The Laos side was slow, we waited 30 mins for a TukTuk (thought it would be a mini van) and then 45 mins for a boat to Don Det. Arrived at 7pm.
Packed a 12 person bus with 19 people and huge bags of rice and other things. The one bathroom break was at a huge open field. No where for my fiancé to use the restroom. Lunch at the transfer spot was good. After that the vans were good.
No complains, the bus was on time on Asian standards and crossing the border went without surprises.
A good service in the sense that it made the border crossing easy. However the advertised time for arrival was wrong by several hours. It was also inconvenient to have a long scheduled lunch break in Stung Treung.
