The following snippet from an article in today’s Thanh Nien News caught my eye:
According to the Vietnam National Tourism Administration (VNAT), only 30 percent of foreign tourists to Vietnam want to return the country, mainly businesspeople coming to Vietnam to study investment and business opportunities.
But director of VNAT’s Travel Department Vu The Binh said, “The number (of foreign visitors returning to the country) is normal, as tourism is mainly about discovery. So, if you visit one country this year, you want make a trip to another the next year.”
Frightening that someone working in tourism can have so little grasp of the importance of repeat business! The real figure of tourists (NOT businesspeople, who should not be counted as tourists) who do actually return to Vietnam is around 5%, as opposed to 49% for Thailand. There are many reasons for this, but one key reason is that Vietnam only seeks to attract cultural or “discovery” tourists, rather than holidaymakers, whereas Thailand has the sense to attract both.
Tourism isn’t just about discovery. It’s about relaxation, sunbathing, golf, watersports, food, fishing, nightlife, and pretty much any other of life’s pleasures you care to mention. Vietnam can offer all of these things perfectly well, but it sometimes seems as if the powers that be are ashamed of this fact! 
To refuse to even acknowledge that the holidaymaker market exists and to settle for such a pitiful repeat visit rate is very, very shortsighted and this, more than any other of Vietnam’s tourism shortcomings, is what is preventing it from competing with Thailand and Malaysia as a major regional player.
