Plan an after party in your exhibit space when the show closes for one hour. First day!!! Hire show services to bring beer, wine, a martini bar, or an open bar. Invite all of your clients and special prospects. Give them each two tickets when they stop over during the show hours or mail them to them with an invitation. This limits what they will drink, makes you look like a big spender with all of the darkened exhibits around you, keeps your budget in line as the show will kick you out after an hour and you are the last vendor these people will see for the next 18 hours. It works every time – we swear on this one!
