Good evening Chris and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
Is there away to add additional information to the RSVP besides just name and email?
Yes, you can absolutely do that by purchasing our Event Tickets Plus premium add-on: https://theeventscalendar.com/product/wordpress-event-tickets-plus/
Although it is typically used in conjunction with an E-commerce platform such as WooCommerce, it also provides the ability to capture extra attendee information on RSVP tickets.
You can read more about it here: https://theeventscalendar.com/knowledgebase/collecting-attendee-information/
Let me know if that helps.
Have a great day!
Geoff B.
