Vientiane to Phnom Penh Destination Reviews

The 12go asia description just mentions a sleeper bus - no other changes of transport during our journey. If there were other travel options, such as bus+van, which we saw when booking, we would not have booked it; we booked this because we thought it was one bus. When we get to the ticket office we were told we switch over once to another van and we would arrive the next day at 4pm, making the trip 20 hours. The trip ended up putting us into 4 different busses over a 27 hour trip, where we stopped to pick up more people when there was no room in the van. Our driver was friendly, but overall this experience was one I hope to never do again.

The first bus took 2 hours longer than it was supposed to for no apparent reason. Due to this we missed the second bus by an hour and I was forced to stay in Pakse for 24 hours for the next bus. The second day with almost no guidance I rode on four different vehicles and arrived in Phnom Penh after a 13 hours, and a total of 53 hours, 33 hours later than expected. The company did pay for my accommodation in Pakse but I would not recommend this route unless you are fine with having ur plans upended for a couple days and spending days in the car.

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.
