"5" star boutique hotels or best accomodations, eco lodges, local markets, meet local people, good food, culture sites, suggest itineraries, highlights. Starting point Hanoi, ending Cambodia. Plan to hire driver/guides with excellent references and command of English language:(suggestions ?), take boats and trains. Any and all suggestions welcomed. We are seasoned world travelers and love to "wing it", get lost, explore, take millions of photos and mostly avoid other tourists ! Please don't send me shopping; I'll do that in Paris !
Thanks all !

I've seen people asking about Vietnamese more and more on Yahoo Answer and many other sites. I do understand why people keep asking about language like Russian, Portuguese or Japanese but see no reason how come Vietnamese is now pretty popular. It's not one of 6 UN languages, Vietnamese people aren't everywhere like Chinese and I don't think Vietnam is #1 Tourists' destination or something. Anyone know?
