If exhibit space is cancelled/reduced by December 18, 2018 or before, the total payment received will be refunded, less a processing fee of $200 per booth. If space is canceled between December 19 , 2018 and January 18, 2019, 50% of the booth fee per booth will be refunded. When the cancellation occurs on or after January 18, 2019, no refund will be given.
