We are a family of five travelling around Cambodia next month for. It's been suggested that we hire a driver for the entire trip. We are planning on going to PP, Siem Reap, Sen Monorom (Elephant Valley Project), back to PP, Kep, Koh Rong (off Sihanoukville), Koh Kong then back to PP. Does anyone know if this is do-able? Any recommnedations.
