As we said in Profit Tip 104, the final day of the exhibit can be deadly. Here are some thoughts on making the last day/last hours as vibrant as the first day/first hours:
Have an actual plan to attract more attendees on the last day. Do not leave this to chance.
Accept there will be fewer attendees on the last day and make this a benefit. Encourage exhibitors to invite their best customers for personal presentations and also tell attendees this is the best day to get in-depth information from the exhibitors.
Make the last day of the paid conference free—for everyone or for targeted groups (such as government or non-profits).
Have special events/sessions that outreach to targeted groups (government, locals, left-handed widget designers, etc.). However, do not make students one of these groups—exhibitors want you to target only qualified buyers.
Force everyone onto the floor from noon on. End the conference sessions, offer free food, raffles, fun events, etc. If you do raffles, be sure to say the winner must be present. And do the drawings in the back of the hall (not at the entrance).
Consider extending the conference one day beyond the exhibit to keep this group in town. And possibly have the awards dinner the last night (with a pre reception in the hall)
