I went to Kenya for three weeks almost 20 years ago. It was awesome. You can't have enough camera if you want pictures. Don't bother taking pictures of animals without a long lens as you end up with thousands of where's waldo where you try to remember why you took the picture. If you don't want to carry a big lens, enjoy the moment and let the pictures live in your memory. I was shooting mostly with 400mm on a crop body and I had one of the smaller setups of people with real cameras. Lots of P&S cameras but the pictures of animals from them are unusable.
I spent some time at Nakuru, Maasai Mara, Amboseli (45C+ in the shade), Samburu, drive through Tsavo, diving at Watamu, climb mount Kenya, a tea plantation (breathtaking green glow off the plants), Sheldrick wildlife nursery (awesome), and some normal tourist crap like visiting markets and villages.
@Evoex Flamingos in lake? If so, probably Nakuru.
