Expo is short for Exposition, normally a fair or show that has items on display for public or trade viewing.
We are heading to the internationally renown "The International Furniture and Interiors Fair" more commonly known as IMM Cologne held at the Koelnmesse Exhibition Centre which is in Cologne (Köln) Germany and run by Koelnmesse GmbH.
Arrived in Düsseldorf Airport you might wonder why Düsseldorf? Firstly it was a direct flight from Glasgow and flights to Cologne (Köln) were all either one or two stopovers. Secondly Düsseldorf is basically only a 40 minute drive to Cologne.
