It is easy to digest

Visual information is much easier to process and remember than verbal input.
A visual presentation of what you are selling will help potential exhibitors to better understand what their options are.

It is engaging

Interactive means that one must be involved. Involvement means quality. So by boosting engagement through an online floor plan, you are rewarded with pre-qualified exhibitors.

It is persuasive

Showing your prospects who else has booked a stand will lead to self-persuasion.
The fact that a competitor is already getting online exposure through your interactive floor plan is an excellent sales argument.
