I like how easy it is for me as an attendee, when registering online! It's also very user friendly so that my co-workers can easily use this system too if needed/wanted by our organization (or not).
The only thing about event orgo i dislike personally would have been having more options available in terms of location choices within one state than another states availability with regards locations; however since they are constantly adding new features every time we update their software there may be something else you're missing out from what other users receive which might make your experience better? Having registration issues solved through using Online Registration has helped us streamline things while at same giving access back into ticketing areas easier then doing manual entry each day leading up prior events - thus creating greater customer satisfaction overall throughout team members who were previously unable do such due lackings before now being able solve them via automation without.
