Koh Samui to Bangkok Destination Reviews

I went from Koh Samui to Bangkok. The transportation was good, no long wait times. The communication was horrible though. I had no idea what to do and no information was given to me about pickups and transfers. I had to call them and they didn’t speak English so had to get someone to help me on the road. I hope the communication improves otherwise it’s horrible.

The Boat ride was good but the bus seating was to tight. I have long legs and there just wasn’t enough leg room.

Compared to the first bus I took last December, the service has changed. There are no more biscuits, only a rice meal and water. Previously, passengers could choose their own seats, but that's no longer allowed. Also, the iPhone charging socket wasn't working properly. Overall, I still recommend this bus service, but I think these areas could be improved.

Loved the journey. Everything went smoothly, comfortable rides on each transport. Got snacks, drinks and a meal on the last but. Emma the assistant on the bus was very plesent and friendly. Travelled with my 8 year old and she loved it too shuch speaks volumes. The only thing stopping this being a 5 star is the aircon blasting through out the whole night trip. It's like it's on full with no way to stop it. If it could be turned.down.ig would make the journey perfect.

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.

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.
