Spacious, clean, air-conditioned van; however, there's no extra space at the back for your luggage, so unless there's space right at the front, you're left having to keep your bag at/by your seat, which doesn't leave much legroom for yourself/other passengers.
Left Kanchanaburi bus station at 8.30am sharp. Picked up a few passengers along the way. A 10-minute toilet & coffee break @ one of its offices. My destination was Mochit New Van Terminal, but as we pass by the company's many offices, I saw many boards where BTS Mo Chit Station is listed as one of the stops in Bangkok. Pointed that to driver, who understood it. Dropped off at the BTS Mo Chit station at 11.20am - note that from this dropoff point, you can also head to the MRT Chatuchak Park.
Would recommend taking the train to Kanchanaburi, and then using this van service to get back to Bangkok.
The operator (Driver) did not let myself and my friend know where to get off. He began shouting and was very rude to my friend. She had no knowledge where and when to exit the bus.
1. The operator was called Kanchanaburi Express, but it is in no way an express bus. It stops dozens of time between the destination for people and packages.
2. The ride was announced 1 hour 50, but once you complete the reservation, the tickets estimate the ride taking 3h. That's just false advertising. Either way, the ride ended up taking 4h, and there were no traffic involved, so I can't imagine how long it can take during rush hour.
3. The seats are excessively small. I'm 5'3" (1meter60), and couldn't cross my legs by lack of space. They're also uncomfortable.
4. There's no space for your luggages (neither overhead or in the boot), if you have a travelling backpack or a rolling luggage, I strongly suggest you buy a second seat.
5. Some people were embarked as there were no remaining seats available. They were in the alley, holding themselves onto the benches and invading personal space as they had nowhere to go in the tiny cabin.
6. The Mochit mini-van terminal has no clear indications once you arrive there. There's no WiFi available. The illegal taxis and tuk tuk around are charging double/triple the price of the course. To get a legal taxi, you need to cross a highway to get to the main bus terminal.
All in all, it's a cheap option, but far from a good one.
