Cost differences between Ho Chi Minh City, Hanoi, Da Nang, and Phu Quoc
Ho Chi Minh City offers the widest dining and nightlife range; Hanoi trips often add the Old Quarter, Ha Long Bay, or Ninh Binh; Da Nang and Hoi An budgets commonly include beach hotels, spas, private cars, and admissions; Phu Quoc requires extra planning for island flights, resorts, airport transfers, cross-island transport, boat tours, and theme parks.
