There is no up front charge but there is a $47 SEAT RESERVATION fee if you don't show up..
If you are unable to attend, it is ok to cancel 1 week in advance of the event and the seat reservation will not be charged. It cost us a lot of time, effort and money to create these quality events for everyone so to protect our interest, we are required to charge a minor fee if the folks don't attend at least 1 day of the event.
