The Go Time feature, which is the portal used during the event itself to check people in and out, has a clean and and easy to use interface, which is great if you have volunteers that are capable but not experts. The import/export feature is a life saver when it comes to updating supporter info. One of the biggest advantages is the option to collect and save credit card numbers when tickets are bought so that attendees don't have to swipe their cards the night of the event. This really speeds up check-in and check-out times. Additionally, the ability to group attendees and assign them to tables takes the headache out of table assignments. They also offer excellent support via phone and chat and I have never left without my question answered or problem solved.
