How far you have to walk from Kidani to Jambo really depends on where your room is. Approximate distances to Jambo:
1. Front door to Front door: 1/2 mile. Besides the buses that run to the parks that you can use to go to Jambo, there is a shuttle that runs front door to frint door usually about every 15 minutes and you can ask for it in lobby. If you walk, it is mostly sidewalk.
2. North Wing: up to about 5/6 mile. Kidani has two wings, north which runs away from the walkway that leads to Jambo and south which runs towards Jambo's front entrance. Those wings are extremely long. The pool is on the north wing side, as is all of Pembe savanna. If you get a room at the end of the north wing, you will be 1/3 mile from the Kidani lobby and thus 5/6 mile from Jambo's front door.
3. South Wong: as little as 1/4 mile. Each wing has three elevators along the wing, one close to the lobby, one about 1/4 of the way down from the lobby and then one about 3/4 of the way down from the lobby. The elevators other than the ones closest to the lobby have names. On the north wing, there is Rafiki about 1/4 of the way down and Pumba 3/4. On the South wing, Timon is 1/4 the way down and Zazu 3/4. The elevators go down to the under-building parking lot, from which you can walk out from the building. The shortest walk to Jambo from the south wing is via the Zazu elevator to the ground floor and distance from there to front door of Jambo is about 1/4 mile.
As to the desire for a "quieter" location, be aware that generally describes all of Kidani as there really is not any noisy location although you can hear some bus noise from some standard rooms not far from the lobby on the south wing if you have your balcony doors open. Otherwise the main risk of noise is simply loud people walking past your door. If what you really want is the shortest walk to Jambo, then you should request close to the Zazu elevator, where the entire area is quiet. But be aware that will put you about 1/3 mile from the Kidani pool. If instead, you want to be near the Kidanu pool, you should request a room close to the Rafiki elevator on the north wing (down that elevator to ground floor gives you the shortest possible walk to a gate to the pool).
As to the rooms, they are dark like the ones in Jambo. You do not say what size room you have. If studio, those are about the same size as Jambo and biggest difference to consider is that at Jambo the shower is in a separate room with the toilet, while at Kidani it is next to the bathroom sink area and can be seen by anyone in that area. It is the 1BRs and 2BRs that make Kidani ideal. They are about 100 sq ft larger than the ones at Jambo, have the extra bathroom, and nicer overall.
