Hi and welcome to our Pre-Sales Channel!
We aren’t able to provide support in this particular forum, but I’ll do my best to answer your question. Our Event Tickets plugin (free) allows for RSVP features, though to work with WooCommerce you’ll need to purchase Event Tickets Plus.
The Event Tickets Plus plugin doesn’t establish events as WooCommerce products, but rather creates purchasable and downloadable tickets utilizing the Woo features. More info can be found on the Event Tickets Plus product page.
I hope this sufficiently answers your question and please feel free to respond with any more questions or concerns you have. Thanks again and have a wonderful afternoon. Cheers!
