How to buy a bus ticket

If you're looking to get some place long distance, then there are plenty of charter buses to choose from in Phnom Penh. We rode along the river front and found a sign for travel and tour and walked in inquiring about bus tickets. It took a phone call from the agent to the bus companies to confirm availability and seating arrangements to Siem Reap and 7 bucks per person later (for a 6 hour ride), we were issued our tickets. Easy as pie.
