Koh Samui to Bangkok Destination Reviews

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.

The bus was great, but the staff was really unfriendly. We were sitting in the last row of the bus, behind us was the wall. There was a little bit of free space where in the beginning some boxes were stored. The bus attendant came to sleep on the floor in that space. He woked us up, by putting up our seats so that he could enter in that little space. I understand that the staff also needs to sleep, but please organise a space for that in the bus. This doesn’t feel like a good service when someone is sleeping on the floor under your seat while you are in a comfortable coach. Secondly when we were getting out of the bus the bus started to drive before we were able to pick out luggage from the luggage department. We took our luggages on the move and the bus drove away with the luggage department open. I don’t know what happened to the luggage of other passengers, but it’s most likely has fallen out of the vehicle on the move Also no announcement where made in english.

We booked the luxury class from Koh Samui to Bangkok, however we didn’t get the advertised screen (no big deal). The seats were quite spacious and could recline. The backrest was on the shorter side though. The dinner was quite standard, but many options including vegetarian.

In Samui you’ll have someone giving you the ferry ticket approx. 30 min before the departure. If you wanna buy food or drinks before the night, do it in Samui : when you arrive at Surat Thani there’s directly a transfer before getting into the bus for the night (we waited for 20mim for the transfer to go because they wanted to make sure everyone was there, then 1h or so for the night bus to arrive). You cannot buy anything there. Bus is like 25people, and you have a break around 0.30/1.00 for 30 min where you can buy drinks and food if you couldn’t at Surat Thani. Still the best bus company for us for night travels.

It was terrible to wait in the middle of nowhere the bus to the Bangkok. From the ferry station the old and scary vehicles to the Surat Thani. Then in this middle of nowhere with padthai for 100 baht also was asked to pay additional 200 baht for the sitting alone.

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.
