Should you be unable to attend, we will accept your written cancellation by no later than 7 working days prior to the start of the workshop, in which event a cancellation fee of 25% will be charged. Thereafter, we regret we are unable to refund any fees, although in such cases we would be happy to welcome a colleague who would substitute your attendance or keep the credit for a following workshop with the same monetary value. All cancellations must please be confirmed in writing. 'No shows' on the dates of the workshop are still liable for the full payment. This clause also applies where we have received your registration form, invoiced you and awaiting your payment.
