I camped for 8 weeks in Africa, did safaris in Serengeti, Ngorongoro, Chobe and Etosha.

It never got old.

But the longest was 4 days in Serengeti. That was enough of driving around in a jeep with sometimes nothing to see for a long time

If you are out safari'ed, there is always Zanzibar and chill out for a couple days after all the adventure.
