The smaller numbers in the group may make the trip a little more expensive but you are more flexible and far more comfortable. Some of the larger vehicles we saw with 15-20 clients would not have gone to the areas we did. Visiting the three different parks was a really good experience as they are so very different in terms of topography and vegetation and animal population. If you want a safari which gives you the best opportunity for seeing as much as possible this is a near perfect itinerary. Even the long road journeys are interesting and well worth the poor travelling condition of some of them.
Botswana offered the difference in spending time on the water (Chobe River and in Delta) which gets you out of the cars and gives you a different perspective but in terms of amount of game viewing both were truly excellent. I did expect to see lions/lioness but to see leopard and cheetah as well on both trips exceeded my expectations.
The big Cat sightings by the end of the Tanzanian trip were impressive : around 30 lionesses and cubs, three leopard viewings, three cheetah - one of which was really close - plus a civit(?) cat. And a lot of these viewings were quite close and brilliant for photographs and - equally important - just to watch and observe and be in the moment.
