The bureau announced its new financial target ahead of a two-day fam trip that will take place on 25-26 March.
It is aiming to attract UK-based corporate and association buyers to the county on a showcase of venues such as Nottingham Arena and Nottingham Castle. The fam trip coincides with the Nottinghamshire Venue Show at the East Midlands Conference Centre.
Nottinghamshire Convention Bureau conference tourism coordinator Andy Melton said: "The 2009 event went down a storm with the travel and hotel-booking agents we hosted. We, therefore, have very high expectations for this year and are confident that the trip will assist us in reaching our £1m target by 2015."
