Please don't put Switzerland in Scandinavia. It is not the same as Sweden.
Scandinavia = Denmark, Norway and Sweden.
The Nordic Countries = Denmark, Norway, Sweden, Finland, Iceland, Faroes, Greenland, Svalbard and Åland Islands.
Scandinavia (incl. Finland and Iceland)You could, however, say, Scandinavia PLUS Finland and Iceland - but that's not what OP wrote.
