Inquiry Submission By Robin R

My daughter and friend are plan to take a day bus from Mondulkiri to Phnom Penh and then another bus to Sihanoukville. (This is a change in plans in response to warnings from this forum about the night buses.) The only company that has buses on both routes is Virak Buntham, which has low/mediocre ratings and a dropoff point from Mondulkiri that seems to be some distance from the pickup point for Sihanoukville. Is there an advantage to taking both legs of the trip with the same bus company–like maybe a shuttle between stops–or does it make more sense to use two different companies with better ratings and closer dropoff and pickup points?
