10/10 experience with HK bus lines. We've been traveling for 8 months and this was by far our best bussing experience. What stood out was the high level of friendly customer service, and the comfortable cabins with working charging ports, massage chair, etc. We boarded in Hoi An and the gentlemen working in the office was so so lovely (I believe his name is Qui but I may be spelling if wrong). He was extremely helpful, great attitude, and eased any concerns we had. I would highly recommend HK bus lines and will certainly book with them again.

We took a day time sleeper bus with HM Happycar from Hoi An to Phong Nha. I received a WhatsApp message from the organizer to ensure we found the bus ok before departing. The bus was extremely clean and in great condition. The little bed capsules were private and lay totally flat, or you could put them into a partially reclined position. I am 5'4" and could lay completely stretched out, my friend is 5'9" and could do the same with flexed feet. There was a USB port, lights and air vents. The driving felt very safe and there were two drivers who traded off which helped us feel safe as well. We stopped 3 times for toilet breaks. After getting dropped off and going about our day, we realized we forgot air buds on the bus. I messaged them via WhatsApp and they responded immediately that they would ask their cleaning staff. They found them and organised a nearby hostel for them to be dropped off at for us to pick up at our convenience. Very impressed overall, would book with them again.
