Leaving for Tanzania in about a week. We have one or two village visits on the itinerary of our itinerary (including Mto Wa Mbu). I've seen the cultural experience post and link on right side of this forum and several forum threads on gifts. Any other general etiquette tips about the village visits, such as re photography, interacting with the local villagers, etc.? Attire tips? One village includes lunch and we have a vegetarian with us, thoughts on how politely to explain if she declines a dish? Any tips to ensure we are respectful during our trip would be appreciated. Apologies in advance if I missed something already posted on topic.
