Bus left reasonably on time and was only a 30 minute journey. It obviously didn’t matter for such a short journey, but the two buses we took for this day trip with Vibol (Kampot to Kep return) were oldest/dirtiest (due to age/cleaning, not trash) minivans we’ve travelled in in Cambodia (comparing with 4-5 journeys with one other company, then 1 journey with another).
