@Myimaginarycathasfleas even if inappropriately dressed, Kate would have coped with the walk from car to church ..... it's about 3 steps, maybe 10 if you're the "wrong" side of the car and have to walk around the back of it. Private entrance to the church, car parked right at the door.
@justasking111 HMQ usually arrives in to Aberdeen Airport on a private flight, and picked up by car for the hour-ish road journey.
