Inquiry Submission By dtatlock

Hello- does anyone have any experience/advice with busses from Phnom Penh to Kampong Cham, and then from KC to Siem Reap? We will be traveling with a family of 4 in early August and are thinking of spending a couple days in Kampong Cham on the way to SR. I looked up options on bookmebus site and see that while there several option to KC, there were some questionable reviews about the Sorya bus company and the Virak Buntham company. Thank you for any insights!
