Hubby and I just got back from our first stay there
We had only requested Sunset Savannah (love my giraffes and zebras) and upper floor. We were on the top floor, north side, steps from the elevator to the lobby. It was an awesome view from up high! You could see all the animals all over the savannah, not just the up close ones. And we got a nice surprise our first night when I could see Wishes AND Illuminations from our deck since we were above the trees. But everyone else is right - I don't think there is a bad savannah view at Kidani! If you have a car, anywhere is a good room. If you don't and will be using the buses, I would request Sunset Savannah near the lobby so your hike to the bus stop with kids isn't so far. We had a car so we didn't care where we were, but it sure was nice to just walk a few steps and take the elevator right to the lobby for refills of our mugs!
Enjoy!
