How Much Does a Thailand, Cambodia, and Vietnam Trip Cost?

Southeast Asia offers great value for money. That's one of the reasons it's so popular. In Southeast Asia, a private tour is an affordable luxury.

Our private tours offer you customized options for couples and families (with our one-to-one travel consultant, you can always get in contact to make changes whenever it is convenient for you), more personal space, a more in-depth and less-touristy experience (different to group tours), and a worry-stopping contingency service (24-hour helpline and free cancellation policy).

  • A typical private tour costs around 200–250 USD per day per person (including airfares within Southeast Asia, 4-/5-star hotel, lunch, attractions, guide and transfers).
  • US$250–350 per day per person is needed for the most luxurious arrangements (all the above with 5+ star hotels).
  • 30%–50% off for each kid younger than 10 years old

Thus, for a private family trip with 2 adults and 2 kids, the average cost for a 3-week trip in Southeast Asia would be about 14,000 to 16,000 USD. International airfares are not included.

For a couple, the average cost for a 3-week trip in Southeast Asia would be about 8,500 to 10,000 USD, not including international airfares. 

Best Times to Visit Thailand, Cambodia, and Vietnam

Thailand, Cambodia, and Vietnam enjoy similar climates because of their close proximity. November to March is the best time to visit with the most sunny and dry weather. Hotel and flight prices rise accordingly however.

One of the busiest times is around Christmas/New Year holiday when hotels and flights are easily booked up. Due to the high demand, you're suggested to prepare your tour at least 3 months in advance. Let us know your interests and requirements, and we'll take care of everything.

If you want to enjoy nice weather without being surrounded by crowds, late October or early April are particularly good times to visit (the times just before and after the peak season).

June to early October is the rainy season in most parts of Southeast Asia. It may cause some discomfort and inconvenience, but lower prices and smaller crowds are the rewards.

Which Country to Enter First?

Flying to Vietnam or Thailand first is usually the most choice, because Cambodia has fewer options for international flights than the other two countries. But Cambodia offers easy access to/from Thailand and Vietnam, so it's good as the middle country.

Thus, the travel route usually goes Vietnam–Cambodia–Thailand or Thailand–Cambodia–Vietnam.

Going to Thailand or Vietnam first may depend on plane ticket prices, the flight situation from your city, your travel preferences, and so on.

Flights from major U.S. cities to Thailand and Vietnam require transfers. It takes least time to transfer via Taipei, Hong Kong, Singapore, or Seoul.

We would work out the best itinerary to match the time of your international flights, leaving time for jet lag recovery and making sure you start your Southeast Asia trip on the right foot.

Contact us if you have any problems. We will give you the best options and suggestions according to your travel time.

How to Travel between Thailand, Cambodia, and Vietnam

Flying is the fastest and most convenient way to travel between Thailand (Bangkok), Cambodia (Phnom Penh or Siem Reap), and Vietnam (Hanoi or Ho Chi Minh City). There are direct flights for these cities. Each journey takes about 1–1½ hours.

We would arrange all transportation within Southeast Asia for you. Your travel consultant would search the flight schedules and book the most suitable connections for you.

What Are the Visa Requirements?

Thailand, Cambodia, and Vietnam all have relaxed entry policies.

Vietnam requires a tourist visa if you're from the US, Canada, Australia, etc. The most convenient way is to apply for an e-visa online. This is a very simple process that just requires you to fill in some information. If you are from certain European countries like the UK, France, Italy, and Germany, you can enjoy visa-free entry.

Cambodia also requires a tourist visa, which can either be obtained online, or when you arrive at Phnom Penh or Siem Reap Airport. 

Thailand allows visa-free entry from 64 countries, including the USA, and the UK, Canada, Australia, Austria, France, Germany, Norway, etc.
