I did a search in the forums for this topic and the latest I found was https://wp-event-organiser.com/forums/topic/bookees-to-edit-their-bookingstickets/
Are there plans for allowing someone to update a booking? I’m not looking for something that is smart enough to adjust payments based on booking changes – although, it would be awesome if it could do that! :). As a first-out possibility, perhaps it could allow bookings for events with free tickets to be updated (ticket count, user address info, etc), and a follow-on release supporting limited update of bookings for events where payments are required.
Thanks!

I have found out how events can be canceled with this shortcode:
[booking_history bookee_can_cancel=”true”]
However, this only works with useres that were logged in when booking. I also want guests to be able to cancel their ticket. Could you add a simple link to the confirmation email with which guests can cancel their tickets?
Best,
Philippe
