You should also invite any other contractor who contributes to the look of your event. Discuss with this group the ambiance you want to create, along with your goals and priorities, the show theme, the types of exhibitors and attendees, and the makeup and goals of the sponsoring organization. Have everyone contribute decorating ideas that enhance the mood you're trying to create. We really encourage innovation, and try to be visually-oriented during these sessions. Try to keep an open mind, and be willing to look at any area.
Most decorators use computer-aided desk programs that can generate many floorplan variations.
You could come up with a new look at virtually no cost. Most show managers agree that it's best to be up front about your budget limitations. If you're open about what you want to create, and how much you've got to spend, your contractor can more easily suggest ways to stretch every dollar. They won't try to oversell you on expensive items. Tour the facility with your contractor, noting the items that may fit the look you're after.
