Vientiane to Siem Reap Destination Reviews

I'm sorry to say but the travel experience was shambles. I chose an option of travel only by one bus to save moving from vehicle to vehicle, but ended up having to change multiple times: sleeper bus, van, another van, third van, another bus. We had to walk between the borders ourselves - in the heat and with all luggage, and after Cambodian border we had to wait for two hours to be picked up being told they don't know how long it's gonna be - maybe 30 minutes, maybe another 30. That was when contacting the agency as there was no one to advise on the other side besides a gent at the only local place there saying that the operators would come at some point. The arrival was to be 17:45 (though someone else bought the trip as 17:00 arrival, another 18:30) but ended up being after 21:00. The gent from the agency and Cambodia drivers were nice, but the staff on the sleeper bus in Laos rude.

For the price wise, the trip were acceptable because we arrived our destination without any accident. But there was too much vehicle changes ,which we needed to carry around our luggage and there was only one break time for lunch. I mean there was no time for toilet and few minutes break to stop by local shop on our way. I respect their hard work of the driver and passengers ,our patient.

They booked me 2 seats on sleeper bus so no-one was next to me and water was given. We left on time. Free tuk tuk from the bus stop in Siem reap to our hostel. The only thing I can criticise is the 2hr 30 wait at a car park in Pakse. Thankfully other girls were on this bus because I would have not wanted to wait here alone at 5am.

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.
