No problem. If you are needing an additional attendant beyond what is already provided with your booth, simply create a new request, select the booth attendant option and tell us how many extra you need. Your invoice will be updated and reissued at 150.00 USD per additional attendant.
If you need to edit existing attendants, you can refer to the post registration instructions on how to insert your attendants in your booth. That email normally comes within 1-2 business days after your registration. If you are having issues with that process, just give us those detail changes and we will do that for you.
