Kidani is pretty intimate and small. If you are traveling with someone who might be more comfortable closer to all the major amenities in the resort put a request on your reservation to be placed close to the lobby. They can’t guarantee to honor this request BUT they are usually pretty accomodating.
The bus stop for Kidani is right outside the lobby and there are wooden benches in that area, only one of the stops is covered by an overhang and there are two benches under it so if it’s raining there is a tendency for people to huddle under that one until their bus comes.
The only problems we experienced with the bus service at Kidani were with the Studios buses. It was SO strange, they took forever and came very infrequently. Not sure if that was a fluke or not.
Otherwise, you should be ok. The hallways aren’t THAT long and it’s pretty easy to navigate.
