The event is set to host 277 senior hosted-buyers from 40 countries, up 19% on 2009.
It will also feature more than 7,500 pre-scheduled appointments, up 17% on last year, with more than 220 exhibitors including destinations, convention centres, hotel groups, airlines, cruise companies, DMCs and technology suppliers.
New exhibitors include Cape Winelands District Municipality, Dragonfly Africa, Turkish Culture and Information Office, Beijing Tourism Administration and the Ministry of Culture and Tourism of Indonesia.
GIBTM exhibition director Graeme Barnett said: "As a brighter world economic outlook beckons, the event is in an excellent position to gain even greater support within the region, and build both its regional and international exhibitor base and buyer audience. At the heart of the event's success is its manageable size, focus on developing business and delivering return on investment."
New initiatives at this year's GIBTM include an expanded professional education programme supported by MPI, ICCA and SITE.
