My trip from Ho Chi Minh City to Gia Lai was with TT bus company, but I wasn't satisfied, so I tried Duc Dat bus company. The driver, conductor, and call center staff were all very friendly. In Gia Lai, someone called ahead to give the driver's number, then I went to the bus station to wait for the bus, unlike the Ho Chi Minh City trip where you have to change tickets. Before boarding, the driver asked for my name and the phone number I used to book the ticket. The bus was slightly late (because some passengers arrived late, so they had to wait for them, but the bus arrived on time). But it ran incredibly smoothly, without sudden braking like with TT buses. The downside: the buses are older than TT buses, the interior isn't as luxurious, but they both have USB A ports for charging. The upside: polite service, no smoking on the bus, individual mini pillows, and a smooth ride.

Took a 4-hour ride in a van today from Nha Trang to Buon Ma Thuot. The driver was friendly and extremely informative about the local culture and attractions along the way. Our previous experience with many bus trips in various areas throughout Vietnam have always been pretty scary as the drivers do whatever is necessary to get around slow traffic. This driver was by far the safest we've seen. We highly recommend using Thai Son's transportation services.

I left my phone on the bus and the bus company returned it to me 💙💙 Everyone was cheerful, enthusiastic, and lovely.
