There is a first time for everything, so don’t worry! It could be that there is a kick-off meeting before your show, in which case, be sure to attend. In general, remember to get off your stand. Meet and greet in the aisle – but without being aggressive. And make sure you get contact details for follow up. A drop box for business cards is a good idea, but it is even better if you keep notes of who you met and what their particular interests are.
