Hey Ed,
I know a guy who runs boutique tailored Safaris in East and Southern Africa...he is a friend, so I am bias, but if you have a budget that allows for a tailorred unique experience as opposed to a mass-market safari with a million other giraffe seeking tourists, then he is your man.
Hayden is a wildlife tv presenter, who now also has this Safari Business...
Does Kenya, Tanzania, Uganda (his current favourite), South Africa, Namibia and more I think...
