Animal Kingdom is our favorite of all the resorts. And Savannah view makes it extra special. It was Animal Kingdom that convinced me to buy into DVC and now I have 4 DVC memberships, with 2 of them at AKL. I own at Kidani, Jambo, BLT and Poly.
In the first week of February, I am going to be staying with some of my family at Riviera (Preferred View) for a week, and just today may 35 year old daughter said, "Too bad we can't switch over to Animal Kingdom. I'm going to miss it, and Zara [her daughter] won't be able to get her face painted, or do the animal activities." But I reminded her I have a room booked for her, her husband and my 2 grand children at a Kidani Savannah view in the fall. And she confirmed again today that she also is going to buy into DVC this year and guess where?
We always go for Savannah View rooms if available. They don't cost that much more than Standard, and yet to me, that is what Animal Kingdom is all about. (Well, that and African decor and folk art and African/Asian/American fusion food.)
I agree that both buildings are MASSIVE with Kidani being especially LARGE.
If you are in Jambo, ask for Kudu Trail, and the Sunset Savannah side of the building, whether you have Savannah view or Standard.
If you have Standard view at Kidani, you will be able to look out over the streets, or over the pool, unless you request a room far far to the north end (about 1/4 mile walk) near the Pembe Savannah, in which case you MIGHT get a partial Savannah View. But I would never do that. Standard View at Kidani, i would request near the Timon elevator, the Rafiki Elevator (the two elevators nearest the lobby) or a pool view.
Of the 2 buildings, Kidani is our favorite. Kidani has 2 Savannahs - the Sunset Savannah (amazing) and the Pembe Savannah, which I will be very disappointed in if I ever have to stay there. Pembe is the smallest of all the Savannahs, and they don't even let most animals wander around there. Not to mention that it is at the far far far FAR north end of the building. Pembe is NOT worth it, if you ask me.
For Savannah View rooms at Kidani, I would ask for the Sunset Savannah, and to be near the Timon or Rafiki elevators. that will get you closer to the lobby and keep you away from the Pembe Savannah (hopefully). Sunset Savannah is the largest Savannah and it is so incredibly nice to just be able to sit out there on your balcony and watch the animals wandering around.
So, yeah, if you are just looking for a hotel room, and you will be gone all day and you never stop to smell the roses, then DON'T bother with a Savannah room. Better yet, go somewhere else. It's cheaper. But if you want the Animal Kingdom Experience then Savannah room is definitely worth it. That is NOT to say that people can't see animals from the lobby or the viewing areas near the lobby, but it just isn't quite the same, and almost nobody bothers.
