Fantastic, organized bus/speed boat trip. Highly recommend. Got a text the night before on wattsapp from the bus company which was fantastic so we had a number. Had to change the pick up point as It was pelting down rain, they were fine about it. Bloke made sure we were aon board, he spoke English. He gave out all the information first in Vietnamese and then in English. We went from Cat ba to Hanoi, had to get off the bus, onto the speed boat and then onto another bus. Well organized, great communication, fantastic trip.
