The people who design hotels need to help guests see the light.
I was sitting in the room of our very nice hotel in the centre of Oslo, vainly trying to read the very tiny print of a city map in order to work out how to get to the Viking Ship Museum, when suddenly I saw the light.
My problem wasn't the decreasing efficiency of my ageing eyes. It was the darkness of the room even though all the lights were on.
Hoping to illuminate things, I first sat under one of the recessed lights glowing dimly in the ceiling high above. Then I put the map directly under the bedside lamp shining feebly beside the bed. Finally I stamped across to my suitcase, got out my little travelling torch, and shone its tiny beam on to the map.
Eureka. I could see. The Viking Ship Museum was on the Bygdoy Peninsula. And the best way to reach it from our hotel was by ferry.
