Delegates took the opportunity to experience other key cities in North America on Day 4 and 5 of the conference, to see some of the major developments happening throughout the country. Each tour – which typically involved a two- or three-day stay in the city (with flights and accommodation paid by the delegate) – embraced a number of the key tall buildings either complete or under construction in the city, as well as some of the cultural sites. The tours, which were free to attend, were led by CTBUH experts.
