The guide were knowledgeable and professional

Hi Mr. Hong,
We planned our entire Vietnam trip though Asia Tour Advisor Co., and I cannot recommend them highly enough. They exceeded our expectations in every respect. Specifically: prompt and responsive to email during the trip planning stage. Mr. Hong customized the itinerary to our needs with great patience (thank you Tra!). all aspects of the trip were as described or better. The guide were knowledgeable and professional.
This was the best decision we made about our whole trip.
