Our family had a great time visiting Vietnam for 2 weeks. The Vivu tour operator is really well organized, honest , helpful and dedicated to customers. Logistics are really good too especially Mrs. Kim Dung, a gem. Prices cannot be better. This 4-5 stars hotel tour has the same price as other tour operator for a 3-4 stars. No kidding. I strongly recommend this tour operator for visiting Viet Nam althought we had a good experience with them with another trip in Myanmar about 2 years ago.
