Feature – A feature is what your product or service or event has or does.
It is a characteristic(s) of the show that is quantifiable and measurable, such as the presence of key buyers with purchase authority, analysts and media, a new industry products pavilion, or hands-on demonstrations of featured products.
Benefit – A benefit is something of value or usefulness.
Benefits explain why features are valuable.
If a feature such as a new products pavilion provides an attendee with a solution, it holds great value—it is an important benefit.
