Istanbul is also one of the world's most exciting conference destinations and is an increasingly popular choice for the world's leading international associations.[35] Istanbul's conference appeal developed with three separate conference and exhibition areas: The Conference Valley (Istanbul Convention & Exhibition Center, Istanbul Hilton Convention & Exhibition Center, the Military Museum Cultural Center and the Cemal Reþit Rey Concert Hall); The Airport & Exhibition District (150,000 m2 (1.6 m sq ft) of exhibition space around the CNR International Expo Center); and the Business & Financial District (with many distributed centers). These cluster areas feature a combination of accommodations, meeting facilities, and exhibition space. They can be used individually, or collectively through transportation with the Istanbul metro, and are linked together for accommodating events with 10,000 or more participants.
