Research what different seasons mean in different parts of Africa before you decide on a destination.

In southern Africa above South Africa (DRC/Zambia/Zimbabwe/Botswana), for example (and maybe further, but I only know about those countries), Feb/March is wet (rainy) season, and animals tend to go completely different places then, and many of the places that are great for viewing animals in dry season are lousy in the wet season, while a very few places (like the usually very dry Central Kalahari) have better animal viewing possibilities in this "wetter season" than the rest of the year). And, in fact, many camps / lodges may either shut down during wet season, or have problems like often-washed-out runway strips during wet season (which you may only realize after thoroughly reading reviews of a particular camp or lodge).

So if it's wet season where you're going in Feb/March, that may greatly limit which places within a country (or even which countries) will be good for animal viewing.
