Honestly, the best bus ride I've had so far has been Mong Cai to Hanoi from 11PM - 6AM. Staff were polite and helpful, and unlike other rides, it was easy to sleep, because the driver wasn't constantly honking. I woke up at 4:30 AM in time for a bathroom break, and the facilities were clean. It's definitely a budget bed, but as a short queen at 159 cm, I was able to fit with my shoes and backpack. USB port works, and with the Viettel 8 gb/day plan, I had plenty to keep me entertained. Water is provided, and the only real negative was a loud auntie on her phone. (not much to do about your neighbours!)

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.
