Is tipping expected in luxury establishments?

While not strictly mandatory, it is appreciated. For private guides and drivers, 15-20 dollars per day is a generous standard.

Should I travel north-to-south or south-to-north?

North-to-south is generally better. It builds momentum from the cultural history of Hanoi toward the modern energy of Ho Chi Minh City.

Planning a Luxury Tour of Vietnam

To plan a high-end trip, prioritize private regional flights to save time and book boutique luxury properties that offer exclusive access to historic sites. Allocate at least 14 days to comfortably cover the country's north-to-south geography without constant rushing.

Secure a Local Virtuoso or Luxury Specialist. Do not book everything yourself. Contact a local luxury DMC (Destination Management Company) that specializes in Vietnam. They provide access to private junk boat charters in Ha Long Bay and after-hours access to sites like the Hue Imperial City.
Use Private Air Transfers. Vietnam is long. Take internal flights between Hanoi, Da Nang, and Ho Chi Minh City using business class or private charters to maximize your time. Avoid long-distance trains or buses, which are inefficient for a luxury itinerary.
Curate Your Property List. Select one 'anchor' luxury property per region. Look for heritage hotels in Hanoi, beachfront private villas in Da Nang/Hoi An, and boutique river lodges in the Mekong Delta.
Book Private Guided Experiences. Request private historians for tours rather than group guides. For food, hire a private chef for a market-to-table cooking class to avoid the standard tourist crowds.
