Among the most popular are priority point systems, in which exhibiting companies accrue points and the company with the most points gets first dibs at choosing space in the upcoming show. Points are awarded based on a variety of factors.
Some shows keep it simple while others have quite complex systems.
It's also smart to include a statement indicating that show management retains the final say on which space will be assigned to a particular company. This protects you if you have to rearrange floor layouts to accommodate an island exhibit, keep competitors apart, or for some other reason tweak the process. Priority point systems benefit not only the exhibitors but also show management. Loyal exhibitors are rewarded for their ongoing dedication to the show, and show managers can build their shows by providing exhibitors with incentives to keep them coming back, increase the amount of exhibit space they take or participate in sponsorship and advertising opportunities. A company receives one point for every consecutive year that it exhibits in the show.
