I always choose Hoa Thuan Anh buses for my trip from Cam Ranh to Ho Chi Minh City. I've used them many times since 2014. I've traveled with many other bus companies, but I find Hoa Thuan Anh buses very smooth, even on bumpy roads. They're much smoother than other buses. The buses are clean, and there's no unpleasant smell. For example, I always have to wear a mask when boarding other buses, but with Hoa Thuan Anh, I don't need to. I've never heard any of the drivers yell at or scold passengers.

Everything was okay, the bus conductor on my trip was very enthusiastic. I have a few suggestions for improvement: 1. Expand the number of pick-up and drop-off points. 2. Check that all passengers are on board before departure. 3. When passengers get off at stops, the conductor could speak loudly (during the day) and gently remind passengers at night (as passengers might be asleep and it would be better to avoid disturbing others). My experience was great! But I only traveled during the day! I hope the bus company continues to improve!
