Comfy bus but AC didn’t work and the bus was full at the connection so we had to wait 2 hours and missed the ferry we were supposed to take. Got there only 3 hours later but still annoying.

Bus was really comfortable and nice beds and curtains! No bathroom which was weird considering how nice the bus was. Made a lot of stops in the night and would just stay parked for long periods of time, also ended up getting to destination an hour before we were supposed to, so we waited 1.5 hours for our transfer instead of 30 minutes, which was a little rough at 5 am but also seems to generally be the way busses are here.

Everything went great with the bus from siem riap to Koh Rong. But the arrival time wasn’t right. The description said we we will arrive at 6.45am in Koh Rong but the first ferry start at 8.30am so you will arrive in Koh Rong at 9.15am. At around 6.45am you will arrive in Sihanoukville and you have time for breakfast (some local cafes are open or 7eleven). The busses were comfortable but take enough clothes for you because it was freezing in the night (for everyone and they didn’t offer blankets). The seats are with fabric, but they will never wash it specially not the pillow which had several stains on it. This was a bit disgusting. I covered my pillow with extra clothes so I didn’t touch the surface! If by you’re travelling together with some friends I can recommend you to book the bus seperatly because then you can have single cabins. If you’re booking together in one booking you have to go in a double cabin which is very small. The stuff was very friendly and we did several toilet stops. No WiFi on the bus

Travelling by bus essentials

  • If you are planning to travel during the high season, weekends, or national holidays, booking your bus tickets in advance is highly recommended. The demand is at its highest, yet very often, the number of coaches serving the route remains the same. The earlier you reserve your seat, the better. On some routes, you need to secure your ticket more than a month in advance; on others, a couple-of-days advanced booking is enough. During such periods, try to book online beforehand whenever possible, as showing up at the bus station without a ticket may result in many-hours of waiting in the queue or leave you downright stranded.
  • VIP, 1st, Gold, and similar bus tickets are the most expensive option, but they provide a higher level of comfort. Normally the price of such tickets will include wide soft reclining seats, blankets, water and snacks or lunch, and sometimes some toiletries. Upper-class buses travel faster, make fewer stops during the route, and normally provide more spacious seating to their passengers and a better travel experience.
  • Not all buses have an on-board toilet, but generally, for all trips longer than three hours, all operators schedule a bathroom and/or a lunch stop. While operators definitely do their best to keep on-board toilets clean, the smell may be an issue sometimes. For longer trips, booking a seat a bit farther from the toilet may be a good idea. Also, using bathroom stops for your toilet needs is always better than trying to find your balance in an on-board toilet on the run.
  • If you travel by an air-con bus, make sure to pack layers. A hoodie, a warm scarf, or a beanie hat may prove a good idea. Air-conditioning on buses tends to be excessive, and running nose and sore throats abound after even not the longest bus rides.
  • Always use the security belts even if your bus ride attendant or driver does not insist on it. Your safety comes first – for you, for sure. All buses normally are equipped with security belts, but they may be fixed behind your seat. Take time to find the belt and fix it appropriately.
  • To avoid being disturbed by overhead lights, switched on during stops even at night, and too loud music or sound from the on-board entertainment system, have earplugs and a sleeping mask at hand.
  • As a courtesy to other passengers, avoid using strong perfumes or smelly foods. Some foods like cheeses or durians are forbidden to take on-board – check in advance. Alcohol is also prohibited on the majority of buses.
  • Note that if the bus requires refuelling en-route, passengers will be asked to get off the bus. Operators are not allowed to refuel with passengers on board due to safety reasons. Usually, it takes from 5 to 10 minutes and is often combined with a toilet/lunch stop.
  • If not stated otherwise in your tickets, arrive at the bus station 20-30 minutes before departure. It will give you enough time to find the departure platform and check-in. For international trips, you may need more time for check-in and border formalities.
