What are the Bus Classes & Prices of Sima Express?
The price of your bus trip will depend both on the destination and the class of your ticket. Note that not all ticket classes are available on certain routes yet for longer trips there is almost always a good choice of options. Opt for a sleeper coach for the most convenient overnight trip. Sleeper buses are usually equipped with berths or soft reclining seats, feature an onboard toilet and your ticket may also include other perks like snacks or even a lunch. Taking a night bus is also a good idea if you want to save on your hotel room. During the day an express service is often the best value for money as it makes less stops than an ordinary or standard class bus and travels faster. On some routes it may be crucial to choose the right class as, say, an ordinary or second class bus may need some 6 hours to cover the distance the first class or express bus travels in two hours!
Pros & Cons of Bus Travel
Pros of Bus Travel
-
Buses usually boast the widest network of destinations covered. They travel to the places you cannot get to by plane or even by train
-
Travelling by bus is easy – there is no need to arrive to the bus terminal much in advance, and the check-in is usually a very fast formality opposite to air travel
-
Bus tickets are very affordable. Yes, there are costly first class or VIP options but is you are on a budget, bus is the first means of transportation you have to think about
-
At the same time, there are different classes of service to suit any budget. If you are after a higher level of comfort, buses get you covered, too.
Cons of Bus Travel
-
Intercity bus terminals can be located outside the city centre in the outskirts. It means you will need to calculate extra time and money to get there. In certain destinations getting from the bus terminal can cost you more than you would expect because only a limited number of transportation companies is allowed to serve the route – and prices may be inflated.
-
During busy weekends or high season buses serving some tourist destinations may run out of schedule and require advanced booking.
-
While buses are not as weather dependent as ferries, bus trips can also be delayed or cancelled due to bad weather or road conditions – keep it in mind if travelling during certain seasons or to certain destinations.

Sima Express Company Reviews

Jeffrey LThe first part was fine, but the second half from Phnom Penh to Seam Reap was the worst. I stuck in the back of the van where it was beyond cramped. That portion of the trip took over 6 hours, which might have been due to the multiple stops the driver made: I counted at least four restroom stops, not to mention the extra passenger drop offs.

Matthew WThere must have been no other customers this day, because we got a private car (BYD with perfect air conditioning) for 2 people. We arrived early, with a 10 minute pitstop, and the transition to the ferry was almost seamless.

Gwendolin Hgood and clean cars and ferries both ways. unfortunately they switched to a smaller car both trips, so we had to sit in the "middle seat" at the rear, which was a bit uncomfortable for all three of us.

Hannah KI booked my ticket so that I would arrive in Siem Reap for 7.30pm however when I reached my transfer in Phnom Penh they told me I would have to wait until 4.30pm for my bus meaning that I wouldn’t arrive until around 10pm. When I questioned this as there was an earlier bus leaving which would have got me to Siem Reap on time the employee just looked at me and laughed. There was no explanation as to why my arrival time was pushed back 2.5hrs and this caused a lot of stress as I was unsure if my hostel reception would still be open on my arrival. I understand that sometimes things change but to have someone laugh in my face and give no explanation was not acceptable in my eyes.

Moritz SAfter taking the boat we needed to waiting for 1.5 hours to get into the bus. After arriving in Phnom Penh we needed to change busses and needed to wait for another hour for it. So we arrived almost 2 hours later then expected and it was just because of the long waiting-times. The busses do not have any leg room if you’re a bit tall so it was not comfortable at all.

olivia Itook way longer than it said. went from sihanoukville to siem reap, it said 9 hrs but it was 12. we were in a decent sized mini bus to phenom penh but then they moved us to a tiny mini bus with not enough room for everyone and their bags. there were bugs in the bus too. the bus driver stopped every 20 minutes, even after everyone on the bus kept asking if he could just carry on driving because we were already late and he just laughed in our faces. wouldn’t recommend.

Kevin BWe paid a little more than we needed to because the transport was advertised as a “comfort minibus”, the photo also appeared to show a type of vehicle that we’ve been happy travelling on before. What we actually got was a regular minivan. I hate minivans, they are the worst kind of transport going for a long journey. They pack you in like sardines, they struggle to fit everybody’s luggage in, the seats are too close together and there is little leg room. In fact, if you end up in the row behind the driver, there is no leg room at all. They are ok for short journeys but are very uncomfortable for longer journeys. I would not have booked this had I known in advance.

nieztego Mixed experience. First part from Hcmc to pp went very smooth, all on time, stops exactly as promised, immigration went very quick also due to help from a driver. Second part from pp to Sihanouk not so good, i was placed in a van and waited there for about an hour until other passengers arrived. We had a substantial delay (1.5 h) and the driver drove very dangerously for about 30 minutes.

Kieron VJourney was good, border crossing went very easy. Only thing is that the bus drivers tried to charge us money for a so called “border fee” which doesnt exist. Also for a visa which we allready had, so that didnt make any sense. Watch out for that!

Aksel RFirstly our driver almost fell asleep several times on the way, as he swerved across the road multiple times. We had to wake him up and keep him awake for the whole trip, which was really scary as we feared for our lives.
Secondly our ferry didn’t go our destination at Sok San. It only sailed to Long Set Pier, which is on the opposite site of the island. They said it was the mistake of 12GO as their company didn’t sail to that port. Therefore we had to catch a taxi to get us across the island which costed 20 USD and a lot of trouble.

Kitti NI had a very good experience traveling from Phnom Penh to Koh Ron Sanloem. It was a very smooth ride, was perfectly organized, we even departed a bit earlier because everyone was there in time. The drivers were super nice, the van had an AC, the ferry departed just in time and we got there as planned. Could only recommend!

Pauline EIt was everything perfect when we arrived to the agency, the start was punctual.
But on the highway one wheel exploded (was it already old and in a bad condition? I didn‘t check the wheels when we left Phnom Penh because I‘m not a mechanical) so it was a little panic in the van. I was afraid of an accident. The driver could par the van on a side way of the highway and he also could change the wheel with some difficulties. We (there were 13 persons in the van - and some didn‘t have a security belt!) were waiting a little bit away from the van when the driver tried to change the wheel. It was dangerous - what happens ig some car crashes into the van?
Finally we we all lucky to arrive to Sihanoukville with the van and the changed wheel.
Maybe the agency should check better the technical condition of the car and the wheels.
For more safety.

Claudia BBus was overbooked, not enough rooms for the amount of bags and people on a small mini bus. Made the bus uncomfortable and the aircon wasn’t great which added to this. We were dropped off at the wrong place and when we tried to speak to the driver to explain we thought it was the wrong place he wouldn’t speak with me or even acknowledge I was trying to speak with him. I am obviously aware there is a language barrier which is why I got up a translation app on my phone to help us communicate but he still wouldn’t listen. We were the given the wrong ferry tickets and the people in the ticket office ended up coming to the port to look for us to explain that we had been dropped off at the wrong office and given the wrong ticket.

Krzysztof PI was terrified when I read the reviews, but I had to take this transfer because it was the only one that suited my departure time. If I had another option, after reading the reviews, I definitely wouldn't have used this company... and... I would have made a mistake, because everything was great. Very comfortable seats, good air conditioning, and the driver drove safely.
I saw in the comments that people were complaining about him picking up other passengers along the way – really? What did you expect, a taxi that would only take you for a few bucks straight to your destination? Next time, take a taxi. You're on vacation, loosen up your roller skates a bit, because I see a lot of tension over nothing here.
