When you book a car, the driver will call to reschedule with you, about 15-20 minutes earlier. Whoever gets in the car first gets to choose the seat first, I got a shared car so I just accepted =)). The car is new, clean, and has comfortable seats for medium-sized people (it's a bit cumbersome if you're eight people). Hmm, the car is new, the air conditioning is cold, so if you can't stand the cold, remember to use a thick blanket to keep warm. The driver drove quite smoothly, but every time he talked on the phone it was quite loud, causing me to wake up in the fog about 2-3 times during the trip but still slept well (luckily I'm fat so I easily wake up and fall asleep). The garage should install a curtain or plastic screen to separate the passenger from the driver, with shelters for both sides. In general, I am very sympathetic to this bus company, so if I go anywhere in Ha Long, I still choose to return to this bus company.
