Hi Michelle,
My family really enjoyed our stay at Disney's Animal Kingdom Villas - Kidani Village. We loved the quiet, beautiful theme, and the villas there are amazing. From our room, we had a savanna view and loved watching a group of three red river hogs wander by each day. Even if your wait list for concierge does not come through, I'm sure you'll have a great time at Kidani Village.
You are looking for rooms that are close to the main lobby, restaurant, and bus stop. Luckily, these three items are all very close to each other.
Sanaa, the restaurant at Kidani Village, is right off of the main lobby. The bus stop is out side of the main lobby and off to one side a bit. From the map, it looks to me like the rooms that you might want to request are those numbered 7204 - 7211, 7300 - 7311, 7401 - 7411, 7501 - 7511, 7212 - 7219, 7312 - 7319, 7412 - 7419, and 7512 - 7519.
If you use online check in, you can add a room request at that time. You can also add a room request by calling the resort directly at 407-938-7400 within 10 days of your check in date. Please be aware that while Disney will try to honor any request, a request is not guaranteed.
I hope that this information helps, Michelle, and please do not hesitate to ask if you have any further questions. Have a wonderful time when you are "welcomed home" to Disney's Animal Kingdom Villas!
