IMEX America, the annual meeting and incentive exhibition, will expand into a second hall at the Sands Expo and Convention Center in Las Vegas for its 2012 show, which will take place Oct. 9-11. When the show debuted last year, just one hall was used. According to show organizers, both halls C and D will be used this year to accommodate increased exhibitor demand. Organizers also say the number of hosted buyers who attend the show will be increased significantly this year, though the total number has not been announced. Last year, the show attracted 2,000 hosted buyers.
