Hi Lynna!
Thanks for reaching out to us! Let me help you with this topic.
Selling group tickets is not a built-in functionality of our plugins. However, if you are selling tickets using WooCommerce, you might want to check out the grouped products functionality that may help achieve what you are looking for > https://docs.woocommerce.com/document/managing-products/#section-11
Additionally, you might want to check out the coupons functionality in WooCommerce > https://docs.woocommerce.com/document/coupon-management/
We always suggest you test these things out before using them in your live site to make sure they work as you expect.
I hope that helps. Let me know if you have any follow up questions.
Best,
Victor
