I read a review that said the bus took 4 hrs instead of 3 and that's exactly what happened to me. Just adjust the scheduled time if that's consistently the case.

VET was Comfortable and professional. On time. I do struggle getting buses from this bus station in PP as it’s so busy and confusing but just have to keep checking with staff to see if the bus has arrived yet.

I initially booked a 35 seater, because i had very bad experiences in palawan, so i wanted to avoid sitting in a small van stuffed with people and luggage. When i arrived at the office they told me they rebooked me to a van, so at first i was not happy about this. But it turned out to be a very spacious van with just 5 people, so I had a very pleasant ride with a very friendly driver.

The bus and the service was very good. Problem was that the journey time said it would arrive at 1.15pm, but it didn't arrive until after 2pm - and there were no obvious hold ups, so I guess the booking / journey time information was wrong

We had a very comfortable bus with a driver and a conductor. The bus also had wi-fi and left on time. However, due to a longer, not so necessary break, the bus arrived a little late which made it very difficult for some passengers to catch their ferry. Also the conductor was eager to help with purchasing ferry tickets and chose the company offering the next trip to our destination, but we rather would have wanted to choose between the different ferry operators.

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.
