Hey Yoko and thanks for getting in touch!
I really wish I could say that reserving a seat is an included feature, but it’s not. We do have an Eventbrite add-on and Eventbrite itself has a seating chart feature–however, that would be available directly through your website with The Events Calendar and visitors would still be directed to Eventbrite to select their seat.
Sorry for the bad news here, but does this at least help answer your question? Feel free to let me know if you have any other questions and I’d be happy to help. 🙂
Cheers!
Geoff
