To hard to pick one as my favourite but as life goes on (getting older) I realize the accomplishments, sights and things ones memory bank accumulates over the course of a few safaris. I have NEVER been on safari without adding a week min to a month+ of extra days travelling, sight seeing and touring. 2 days on a plane to get there, life is too short not to really see, immerse and feel as much as possible while there or even on way there or back.
Here are some things that stand out in no order;
Shark diving in SA, Penguins in SA & Namibia, Namib desert/dunes, Kruger, Hwange, Etosha, many smaller parks in all 3 countries, table mountain, Himba Village, schools/orphanages, ancient coliseum in Germany, whine on the Rhine, sunset cruise on the Zambezi, local seller markets, world food styles and types, carving "towns" or even a walk/drive to see so many people not so lucky, as in Ethiopia. These are but a few. Yes never visit Zim without a few days in Vic Falls, even 2 weeks was great when SAA had their strike and "stranded" us fully paid at Elephant Hills Hotel.
I think tourist things and world sight seeing only adds to safari and certainly wakes you up to how good one really has life. Grateful and humbling. I cannot even imagine those who fly over for a 7-10 day hunt and then its back. Or those who finish early, reschedule and leave early. That's never been me.
