Educational Trip for Village Kids

I am a currently serving Peace Corps volunteer. I live in a rural village in the Northern Province of Zambia. For the past two years I have been tutoring 5 children, all of whom have become my best friends. They range from ages 6 to 12. I want to take them out of the village for a week long trip and show them Victoria Falls, a museum, crocodiles and wild animals and show them the importance of not only education and learning english, but also the importance of conservation. For almost all of these children it will be their first time out of the village. These kids will see things they have never experienced before...washing machines, restaurants, etc and I want to show them a quality of life they have never before experienced, to motivate them to do well in school and try hard in life.
