A quick summary, and I apologize if I say things you already know! AKL is partly DVC, partly cash. There are 2 sides to the resort. Kidani is all (mostly) DVC. Jambo House is mostly cash but also has DVC rooms. So the resort itself has been open, but only for DVC stays. When we were there in March, both pools were open, the main restaurant on the Kidani side, Sanaa, was open, but with reduced options. The counter service spot at Jambo House, The Mara, was only open for grab and go items in the morning. I believe that The Mara is also open for lunch items. But the main restaurants in Jambo, Boma and Jiko are not yet open, and I've not heard anything about when they might open. That being said, if they are opening up Jambo House for cash guests at the end of August, I am certainly hoping they are going to make plans to open one or both of those restaurants.
The animals absolutely are out and about. Some of the rooms at Jambo have savanna views where you can see the animals. Some do not. When we book rooms through DVC, savanna view is a category of room we can reserve. If you're doing cash for the room, I'm not sure how you request savanna view - but that's something a lot of people would want, I'm sure. I'd call guest services to ask about that. If possible, you'll definitely want the balcony overlooking the animals - you just cannot beat it. But if you can't get a savanna view, there are locations around the resort where you can still see many of the animals.
Finally, AKL is a bus-only resort (unless you have a car). That transportation is absolutely running. If you have a room at Jambo House and want to have dinner at Sanaa on the other side of the resort, it's a reasonable walk to the restaurant - you won't need to worry about transportation for that, unless you need it. Then you can hop a bus to go between AKL hotels. Enjoy your stay - it's one of our favorite resorts to stay anywhere, not just WDW.
