The typical stand attractor will be something you'd see on a street corner. A busker, a magician or someone tying balloons into different shapes and they are all well and good, but I believe you need to link your stand attractors very very closely to the message and theme of your stand. So balloons only make sense if the shapes that they are being tied with them link into your brand, your colours your stand theming. Far better for me, are themes and attractors which link to a longer term message, a longer term strategy. So for instance, within the show environment there are likely to be a great sample of that market place. Why not ask them some questions about where their business is going, where they are personally going, where they see their needs being in the future. That is giving you market intelligence and a survey which you can interact with them about. That for me is a very effective one. I would also say though, because of my passionate belief that the people are what makes stands work, that actually good old fashioned hospitality is no bad thing. That doesn't need to be booze. Although, if you want to oil the wheels of commerce, it's very effective, but simply entertaining people, some refreshments, some nibbles and so on. Using those to hold people and make a more relaxed, a more intimate dialogue, that is very effective. Simply sticking a bowl of sweets on the corner of a stand and hoping that people are going to march over and interact with you doesn't work.
