Hi Scott,
Unless you have marked events as “Private”, users will see all events on the calendar whether or not they are logged in. Besides the output from the shortcode you mentioned, logged in users will see the option to view their tickets from a single event page (see screenshot) – you can read more about how this works here – but otherwise, the calendar and events will look the same for logged in/not logged users.
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Tickets Plus for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
