I assume you mean Kidani from your post but the villas are also in the Jambo building on the fifth, and for club level, sixth floors. The u-shaped Jambo building itself has long walks from the end rooms to the lobby, longer than the walks can be at BWV from lobby to last standard view rooms. The distance is not the best but it is not completely awful.
However, there is Kidani, which is a different story. Kidani has two wings, north (the one the pool is on), and south (the one that runs toward the front of Jambo and has the bus stop). The south wing is a little shorter than the north wing. The tip to tip internal walk is about 2/3 mile, lobby to end room on north wing is just over 1/3 mile. What does it compare to? Picture yourself walking over from Future World at Epcot to the base of the World Showcase. Now turn left and walk to Germany which is a little more than 1/3 mile away. You can actually take a boat to do that at Epcot. Kidani has no boat, but many who get those end rooms have rental cars and they actually drive to the lobby when they need to go to the store or front desk. In fact, that is Kidani's saving grace, an ideal under-building parking lot that runs almost throughout the entire building, with three elevators along each wing so that no matter where your room is you can always park fairly close to it.
As to distance from Kidani to Jambo, it again depends on where your room is. Front door to front door is about 1/2 mile; end room on Kidani north wing to Jambo front door is about 5/6 mile; from Zazu elevator, the last one on the south wing at Kidani, to Jambo is about 1/4 mile. You can take the bus -- park buses usually stop at Kidani first then Jambo, while Disney Springs bus goes Jambo to Kidani. There is also a shuttle that runs between the buildings that you just need to request at the front entrance.
Standard view at Kidani provides some protection from the longest walks simply because on the south wing the standards are only in the first four building units from the lobby. On the north wing, they are in the first three units from the lobby, and part of the fourth and the sixth building units which have standards converted from savanna view rooms. The ones in the sixth have very long walks but still about 200 yards short of the end rooms. Requests for either savanna or standard view that can make the walks to amenties bearable are "near the pool" or "near the Rafiki elevator" which will get you a room on the north wing (down the Rafiki elevator gives you the shortest possible walk from building to a gate to the pool area). Request "near transportation," "near Community Hall," or "near the Timon elevator" (down that elevator to second floor gives short walk to the door that is closest to the bus stop), all of which would put you on south wing with reasonable walks to amenities.
