Hey Debbie
Thanks for reaching out to us!
You can definitely integrate tickets for our recurring events. There will be a single ticket used for all events within the series of recurring events. So, for example with your scenario above, you would create a recurring event covering Friday, Saturday & Sunday for three weeks. When you create tickets on that event, those tickets will be what is displayed as available for all three weeks of the events.
I hope this helps. If you have any further questions that I can help with before making your purchase please don’t hesitate to ask.
Thanks!
