I would like to address some of the points you brought up in your review that you did not mention during the trip.
You are worried about being insensitive to the villagers, as am I.
I have been to these villages many times, usually with my vietnamese partner/interpreter to talk with and work with these people, they know me, and I work hard to NOT be an irritent.
I do NOT just walk into the houses, If the doors are open I might poke my head in to say Hello, which is normal and accepted, as they have differnet concepts of privacy than we do in the west.
Many times we are invited into the homes for some tea or snacks.
I do NOT demand anything from these people, we are thier guests, sometimes I will purchase things from them such as fruit, handicrafts, or textiles, as a way of giving back without just handing out money.
I rotate which villages we stop at. We try not to visit the same village more than once a month, because I do not want to interrupt the lives of the people too much.
Yes, I did pick up a piglet so you could photograph it, and the woman who owned it was standing right there and thought it was funny watching me get dirty catching a baby pig.
Yes, I did snap a small branch off a bush when we stopped at one village. I know now not to park in that spot. It was the first time I had been to that specific village, they had just built a new bridge that gave it road access, you were very happy to be the first tourist ever in that village and all of the women were happy to see you and were checking out your nail polish. I have no idea why you are saying the adult. are unfriendly, on my tours we see nothing but smiles from people of all ages. I went back then next week with my interpreter and apologized for hurting the bush.
Most people comment on how nice the teeth are of the villagers, they only eat fresh food, no fast food, no processed food. I do not do tours every day, nor do I give every child candy every tour, at most these kids get maybe 3 or 4 lolipops a year, which, except for red dye#4, I do not think is much different than the raw sugarcane they are always munching on.. As for the older people, they are reminded of when the americans drove around during the war handing out food and candy, but you did not bring any of this up during the tour, you happily handed out candy and took photos. If you have ANY photos of children with rotten teeth, please send them to me and I will take them to the dentist myself, I am here to help the people of vietnam, not ruin their health.
The villages in Sapa are very beautiful, but they get hundreds of visitors a week, and get constantly interrupted to pose for photos, There are many good tour guides out there, but there are many tour guides who come from the government in the big cities to keep an eye on the villagers and ensure they do not stray from the script for the tourists.
The villages we visit get almost no tourists and just go about their daily lives. We stop by maybe once a month and say hello.
I am sorry you did not enjoy your tour as much as some of my other customers. I thank you for your feed back, and as we go back through the villages I will continue to work with the people to ensure it is a positive experience for both sides.
