Excellent overnight bus trip from Hoi An to Da Lat with Viet Lao. The staff was very friendly, the bus was clean, the driver was a good driver, and there was no music or unpleasant noise. All this at a good price with smooth communication in English, so I recommend it. For first-timers: there are no toilets, but there were three stops approximately every two hours (you are notified in advance by announcement). You cannot eat on the bus, but there are restaurants and snack bars at some stops. You must remove your shoes and walk barefoot. At the stops, plastic slippers are provided as you exit the bus; you return them to a bin before reboarding. A small bottle of water, a blanket, and a pillow are provided. There is a USB port. I couldn't get the Wi-Fi to work, but that might be my fault. For those who are overweight or very tall, I recommend taking buses with fewer seats (there were about 35, and I'm not overweight, but it was a tight fit). I recommend the lower and middle seats.

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.
