It is worth doing the tour if you have some time in Nairobi and want to get a first impression of a safari. Except for the leopard, we saw all other four of the Big Five in Nairobi National Park, including lions after the hunt and 2 x mother rhino with child. In my opinion, the breeding station for young orphaned elephants is a must. Being eaten out of your hand by giraffes in the giraffe park is a special kind of experience. The guides were nice and catered to our special requests. One of us advanced the money for an entry, where we had to pay with dollar cash, until we later had an ATM to return the money in.
