We are going on a 5 day camping safari leaving the 28th September and are looking for others to join. (So far we are m34, m31, f28)
We have booked with TrekTZ (http://trektz.com/) on the recommendation of a friend who used them and they have been great so far. The cost is around $200 per person per day.
We will be visiting the Serengeti, Ngorogoro Crater, Tarangire, and Lake Manyara.
Please PM me for more details if interested!
