My husband also has had a stroke (about 40 years ago) from a shattered right tibia and we have stayed at KV several times. You could request closer to the lobby area to make your walk a bit shorter. But there are places to stop and look at the animals along the hallway, so you could stop and rest if you need to. If you have your own car, you can park under the building closer to an elevator that comes closer to the location of your villa.
