I don't think the kids explained this properly. DD did the trip to Kilimanjaro when she was 16. It was organised by her school in conjunction with a company called World Challenge Expeditions. The cost of the trip, including inoculations and kit was paid for entirely by the parents.
The money raised from supermarket bag packing, car washing, fetes, ceilidhs etc was spent entirely on assisting kids in a Tanzanian village where they stayed for a week before travelling on to climb Kilimanjaro.
I can only speak of my daughter's experience and she loved every moment of her adventure.
They travelled from the UK to the Netherlands and then on to dar es salaam, picked up provisions and then on to a village where they stayed for a week helping to paint the school and handing over the money raised by their fundraising events. This money was to be spent on equipment for the school.
After a week in the village they travelled on to climb Mount Kilimanjaro, then on to visit a Masai village in Kenya. After that they were on safari and finished the trip with a few days in Zanzibar. The entire trip took a month and was the first time she has travelled abroad without us. I fretted and worried the entire time but she absolutely loved it and gained numerous life skills.
So, unless this type of trip has changed, I can safely say that the charity donations raised by these kids at their fundraising events will be spent on helping underprivileged children in Tanzania.
