Hi Jonathan,
We unfortunately do not have a public demo of such features at this time. The only demo we have a is front-end demo at http://wpshindig.com
We hope to roll out a back-end demo to let folks test out ticketing functionality and the like some time in 2017, if all goes to plan—but for now, the closest thing we have to a trial/demo period is our thirty-day, no-questions-asked refund policy. Many people use this time to try the plugins firsthand on their site—if they don’t find them to be the “right fit,” they request a refund in full and move on to another plugin.
You can learn more about that policy here ? https://theeventscalendar.com/knowledgebase/refund-policy/
I hope this helps!
George
