Until at least the end of June you can register your show for free so the following will only be relevant if you register after then & we need to resume entry fees.
It depends what you mean by two (or 3, 4, 5 …) shows.
If you mean you want to run the same show on successive days, the timetabling software we’re using calls that a recurring event and we count that as the same show.
If it’s improv, no two shows are the same, but as long as the title and description are unchanged , it’s one show to us. no extra payment.
If you mean you want to run the same show in more than one season during the festival (e.g. to cater for different time-zones), our software will treat those as different shows, but as long as the title and description are unchanged we will treat them as one show, no extra payment.
If you are producing two shows that look different to potential audiences then, yes they are different to us as well, you’ll need to pay twice.
