I really enjoyed this trip. The driver was always on time. I did not expect this at all, but we were well fed, treated to sweet biscuits and provided with water. It was very pleasant. In addition, there was a warm blanket on the bus. All the people who provided the trip were kind and polite.
Our driver, was right on time. He let us make individual breaks :)
The music was nice and bus was comfy! He even showed us a view point. So we had all in all a really good trip
Good nice driver (he was doing everything himself - no assistant). We arrived on time, maybe even a bit early. However, rather old bus with basic comfort. No plug to recharge our mobile phone. Bottle of water and a little bit of food provided - no meal.
First was put on a rather new and comfy bus with seats layout 1+2. If you get the single seat it's very nice (seats number 1, 4, 7, 10, ...).
BUT 5 minutes before departure they figured that I am supposed to take another bus, which was older, less comfortable and spacious, and had 2+2 layout.
On top of that, departure time from Nong Khai in the ticket was 19:00, however the bus is scheduled for 19:30, and the actual departure was 20:00.
Arrival time to Bangkok in the ticket was 4:15, actual time was closer to 5:00.
The service and the staff was nice and friendly.
