Koh Samui to Bangkok Destination Reviews

Comfortable seat, friendly assistance in person and on Whatsapp, quiet environment, smooth and safe travel without delays. There is wifi which works quite well on the bus and a USB port next to each seat. Ferry ticket and dinner are included. Overall, much better than other bus companies in Khaosan.

I had a return trip with TravelBus Asia between Bangkok and Koh Samui, and I strongly would like to recommend TravelBus Asia to everyone. Members of staff at their Khaosan Office as well as bus attendants were very professional and friendly. They spoke very good English, and all announcements were made in English, which I have found traveller-friendly. Before departure, they gave us all detailed information on the bus journey, including when, where and how long we were going to stop for a short break for toilet. Check-in usually starts 1 hour prior to the scheduled departure time, when you depart from their Bangkok Khaosan Office. Complementary tea and coffee are available there. Also, a quick evening meal is included. (If you arrive the office earlier, you can leave your luggage there and walk around Khaosan Road if you want.) When I returned to Bangkok from Koh Samui, our coach arrived at around 4:30am. They kindly allowed me to use their office to wait until the first public transports start in the morning. Again, hot tea and coffee were available there even very early in the morning, and I managed to feel refreshed when I used their washroom to wash my face and brush my teeth after a long night-bus journey. It was a very comfortable round trip, because the coach had a toilet and tea/coffee making facility available on board. Also, a USB port is equipped, so that you are able to charge your SmartPhone during the bus journey. Onboard WiFi worked perfectly, too.

No instructions on what was to happen. Waiting around without knowing when we were getting picked up. The ferry left 2:30 not 3 as stated. Coach was freezing cold with no way of changing temperatures. You stated one case one hand luggage. 2 ladies got on with lots of bags and cases that were stored by us and kept falling on to us. Worst travel we have done. I called and what’s append your customer service and no reply 😡

The „VIP Bus“ is not what was shown during the booking. There had been 4 seats in a row, not 3 as shown. The bus was very old and dirty. The personnel was rather rude and had minor English skills.

We went from Koh Samui to Bangkok, first by ferry and then by bus. The whole experience was super smooth. As soon as we arrived at the Surat Thani Pier, we already saw the bus (it was easy to find, don’t worry). The bus travel was very comfortable, it was easy to sleep and we stopped around 7pm to have dinner. The VIP bus was spacious and comfortable and we arrived exactly on time in Bangkok.

I booked a vip bus to be comfortable to sleep during the journey and they did o erbook it so we ended up me and other people on little bench in the down part of the bus with the luggage. Very uncomfortable and impossible to sleep. The toilet was also not usable.if I wanted this kind of experience I would have paid for a low cost ticket. The changes were fluent tho and quite well organized.

Note that the travel time is for your reference only and can depend on different factors such as traffic and weather conditions. Heavy rainfalls almost inevitably make the trip longer due to poor visibility or floods. Road and surface repairs which happen quite often, result in detours and longer travel times. Major national holidays, long weekends, or peak season periods may cause delays both in departures and arrivals – plan accordingly to avoid disappointment, especially if you have further connections and a tight schedule.

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.
