Hey I am planning a Laos trip in December. I really want to visit some villages that are not overly touristy(I realize the sad irony that my visit contributes to making these places less authentic, but I have tried to be considerate to locals in my previous travels) I'm totally willing to sacrifice so called western comforts of fine lodging and custom cuisine.
Since I will not be booking in advance, I am trying to figure out my best chances for finding an appropriate tour on arrival.
Based on trekking reviews, would you agree the order is Phongsali>Louang Namtha> Oudomxai > Louang Prabang for the type of experience I am looking for?
Also, should I be bargaining much on the tours? With the ecotourism breakdown of how the money gets spent, I would only really want to bargain down the profit to the company...
Actually, what things in Laos (& Thailand) should I use the set price for?
Are there any recommended gifts to the host villages?
Is it customary to tip guides? (I have before in France and Kenya)
Thanks for your help.
