Event ticket cancellations must be made no less than two days (48 hours) prior to the event start. So, if an event falls on a Thursday morning, you must cancel before Tuesday morning that week.
If you cancel after this, you will still be charged the full cost of the event – an invoice will be emailed to you for payment. Similarly, there is no credit for payment on the online payment system should you decide not to attend within this 48 hour window.
Sponsors not attending an event cannot accrue their complimentary tickets from one event to another.
