Gatwick Airport in London has to be one of the coldest in the world. Not by virtue of being in the coldest place in the world, but just general lack of heating everywhere. Has anyone else experienced this? Go in the tube from Terminal South to Terminal North and you just about freeze. Enter Gatwick and there is very little insulation at the main doors. The entrances are all freezing cold. Wait for a bus and if you are lucky you will get some form of shelter, but no doors or heating in it!
