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.
