I took a bus from Nha Trang to Ho Chi Minh City. In general, the bus went quite quickly and arrived earlier than I expected. The driver was also enthusiastic and polite, calling in advance to confirm. People should proactively call and ask the bus company to confirm all travel date information and ask them to notify them in any case of schedule changes. When getting on the bus, a few people wondered why the seat wasn't a bed. You should carefully check the type of seat on the online booking ticket because I saw it clearly stated it was a seat. The bus company will call to confirm the trip time and license plate number. Please remember the license plate clearly to catch the correct bus.
