Just a tip.
In many places you read that:
a) game viewing in Kenya is one traffic jam after another
b) you should go and see Masai Mara if you want to do wildlife viewing.
Actually, it's Masai Mara where you bump into one vehicle after another, and where Masai warriors will stand next to a resting lion to defend it from tourists. If you don't mind that, go to Masai Mara. If you prefer something different, go to Tsavo East or Shimba Hills (they have a gorgeous tree top lodge!). In both parks we saw so many animals, and the only time we ever saw other vehicles was when there was a cheetah sighting. And we were there outside the low season!
