I took the 16-seater mini bus in the morning from Siem Reap and had an uncomfortable ride crossing over the only border that is currency open between Cambodia and Laos (I do not know the name of the place). From the Laos side, I changed to another bus and sat for another 3 hours before I finally reached Pakse, south of Laos, at about 8pm. I stayed in this Japanese owned FoRest Hotel & Restauarnt for 2 nights. Pakse is not a recommended place for tourist.
