Vietnam's airports at Hanoi, Ho Chi Minh City, and Da Nang serve a country where the transfer from terminal to old quarter hotel involves specific route knowledge. Hanoi's Noi Bai Airport is 45 kilometres from the Old Quarter — a pre-booked transfer handles this more cleanly than roadside negotiation, particularly for late arrivals. Ho Chi Minh City's Tan Son Nhat Airport sits inside the city, but District 1 traffic and the specific address system of the Bến Thành and Phạm Ngũ Lão hotel districts require a driver who knows them. For intercity transfers to Hoi An from Da Nang Airport or to Hue from either direction, pre-arranged road transport with timing coordination is the sensible approach.
