I went with 4 tickets on November 13, booked sleeper bus tickets, the bus company advised me to go with a double cabin without extra charge, very enthusiastic and thoughtful. The sleeper bus is comfortable for 2 people, with a clean toilet on the bus. Thank you bus company.

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.

I went Hoi An > Saigon. I was cautious after reading the reviews, but it worked out okay! They have a premium bus, but the service and employees are definitely not premium. But they're very effective and competent. They have an actual office in Hoi An, which is nice. A nice shuttle took us ftom the office to the highway where we met the bus. We stopped for dinner at a cheap, good enough spot at 8:30pm. They must have sped through the night because we reached the northern part of Saigon at 6:45am (at their carwash facility?), where they loaded us on a very janky shuttle bus to transfer to the Tinh Binh office closer to downtown (not enough seats, so some people sat on plastic chairs in the cargo hold). We reached there at 7:30am -- much earlier than the 11am arrival time on the ticket. I'm 178cm and the seat was extremely comfortable; I ended up sleeping straight from 11pm until we arrived to Saigon. But three negatives: - Second shuttle bus was blatantly unsafe (see pic) - My seat was stuck in recline / couldn't sit up - Daytime driver played rock music on a high volume. Thankfully he turned off the rear speakers when asked, but be careful getting front seats. Overall I would take them again as long as it is a budget price.
