We went by bus at 19:30 Danang - Nha Trang. The blue illuminated bus looks like a spaceship of the future. Super comfortable! If possible, take the top bunks, and in the middle of the cabin (at least the second row from the drivers, because they can smoke and chat the whole trip) and at least the second row from the toilet (it may smell). We had a clean, comfortable toilet, modern leather seats, and blankets. The driver drove moderately, did not honk excessively at night and did not brake sharply. We slept well) at 4:30 we arrived at the station near Nha Trang. There everyone was asked to get out, given their things and put into a Sprinter, which went to the center of Nha Trang. Due to the fact that this nuance with the transfer was not agreed upon in advance, it naturally raised many questions from passengers. But the drivers don't speak English. They only show you with gestures where to go)) And they literally forcefully transfer you into the sprinter so that you don’t get lost)

Going on the 4th so it wasn't too crowded, it was ok so book a 24-seat limousine for more space.

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.
