Great experience!! The bus from start to finish was amazing, the bus was new, very clean and the seats recline to almost laying down. The bus driver and other staff were very helpful, friendly and they spoke great English. I was very comfortable the whole way to Bangkok, we stopped twice for food and arrived an hour early. My only constructive criticism is about the first food stop which left me a little disappointed- I have a rare medical condition, it’s an autoimmune disease I have take three different types of antihistamines throughout the day/while eating as I am allergic to almost everything but some foods cause anaphylactic shock. I had some issues arise before boarding the ferry which prevented me from getting some food for my trip. So when we arrived at the first stop, I tried to ask the only food stand for ingredients in the fried rice, she looked immediately looked annoyed of me, then spoke to the other person working her who then gave an uncomfortable glare and proceeded to ignore me. I asked again and they both ignored me again. I was so hungry, and could not eat for 6 more hours. The next stop happily got me steamed rice and fried eggs because I could eat the other food that was available, and she did it happily (I tipped her) I have lived in Thailand for two years, many many Thai people have read my phone with a smile and help with my food requests.

I booked a ticket from Samui to Khaosan road, but they dropped me off at Ratchadamnoen road and I smelled weed all night long. Will remember this company and won’t use it again

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.
